Ram cruiser tank Mk I, Mk II (early), Mk II (late) and Ram OP Mk II tank - case report

Tankers!!
      This time we will see some Canadian Girls who are unfortunately forgotten by the Big Manufacturers of injected kits: Ram cruiser tanks.
      I'll show to you guys the three best-known armed versions of this tank: the Mk I and the early and late versions of the Mk II...
Ram mk I with 2pdr gun
Ram Mk II early with 6pdr gun Mk III (43 caliber)
 Ram Mk II late with 6pdr gun Mk V (50 caliber)
      ...and the Ram Observation Post vehicle (Ram OP). This kit I will present to you guys as case report.

History:
      The Tank, Cruiser, Ram was a cruiser tank designed and built by Canada in the Second World War, based on the U.S. M3 Medium tank. Due to standardization on the American Sherman tank for frontline units, it was used exclusively for training purposes and was never used in combat as a gun tank. The chassis was used for several other combat roles however, such as a flamethrower tank, observation post, and armoured personnel carrier.
Medium M3 Lee - The beginning ...

Development:

      Even before the loss of the majority of the United Kingdom's tank force in France in 1940 after Dunkirk, it was recognised that tank production in the UK at the start of the war was insufficient and capacity in the US was taken for British needs. So it was necessary that if Canada was to equip with tanks they would have to be manufactured locally. In June 1940 the Canadian Pacific Railway's Angus Shops in Montreal - as the only large firm with spare capacity - had received a contract to produce 300 partially fitted out Valentine tanks for the British; this was followed later with one for 488 complete tanks for Canada.
      However the Valentine was an infantry tank and Canada required a cruiser tank for its recently formed armoured division. In the end 1,940 Valentines were produced by CPR most of which were supplied to the USSR. Although the Valentine used a number of American produced parts, its reliance on British components, difficulties in adapting its manufacture to North American methods, and other problems such as limitations to the availability of the right type of armour plate affected Valentine production. The Canadian Joint Committee on Tank Development concluded, in September 1940, that its cruiser tank should be based on a US rather than a British design.
      The Canadians were interested in production of the M3 Medium. However the M3 was an interim design and lacked a turret for its main armament. In early 1941 the Canadian Interdepartmental Tank Committee adopted a compromise: to develop a superior design locally but using the M3 chassis. The British Tank Mission which was involved in the modifications of the M3 for British use contributed a tank expert - L.E.Carr - to design a new hull and turret for the Canadian tank, which could take a 6-pounder (57 mm) or 75mm gun while retaining the lower hull of the US M3 Medium.
The Ram upper cast  hull
     The new hull was cast rather than welded or riveted and lower than that of the M3. The pilot model's casting was produced in the US by General Steel Castings and later they aided the set up of Canadian production. Montreal Locomotive Works (MLW) was chosen to make the new Canadian M3 Cruiser Tank (as it was then known) and was given the funding to set up the Canadian Tank Arsenal at Lonque Pointe.
Ram prototype
      The MLW was a subsidiary of the American Locomotive Company, which had experience in producing large castings and another ALCO subsidiary was producing cast hulls for the M3 Medium.
Rams under construction - We can do it !!!
      Canadian engineers ran into many challenges when developing the tank as Canada had never produced a tank before. Along with the lack of knowledge, it took time for Canadian factories to gear up for the production of many of the Ram's components. Initially Canada relied heavily on United States and British materials to complete the construction of the Ram. Most critically the Ram's Continental engine and transmissions were available only in the USA and these were always in short supply. The Ram tank was developed with a turret which unlike the US M3 could traverse the main armament 360 degrees.
Turrets under final construction
      Its fully cast armoured steel hull gave reinforced protection and - with the driver's seat repositioned to meet British requirements for right-hand drive - lower height while the US designed chassis and power train ensured its overall reliability.
      Although it could mount a US 75 mm gun, the preferred armament for the Ram was the QF 6 pounder which had superior armour-piercing capability. As it was not immediately available, early production (50 tanks) were fitted with the 40 mm  2-pounder gun.
Rams Mk I with 2pdr gun - initial production line...
      A prototype Ram was completed in June 1941 and general production of the Ram I began in November of the same year. The Ram I and early Ram IIs were fitted with side doors in the hull and an auxiliary machine gun turret in the front.
Ram Mk I with 2pdr. gun
Ram Mk II early with 6pdr gun Mk III (43 caliber)
      The former weakened the hull and complicated production and the doors and the machine gun turret would be discarded in later modifications. By February 1942, production had switched to the Ram II model with a 6-pounder gun and continued until July 1943.
Ram Mk II late with 6pdr gun Mk V (50 caliber)
      In March 1942 a decision had been made to change production over to the automotively-similar M4A1 Grizzly cruiser tank, the Canadian built Sherman -  for all British and Canadian units. Ram production continued due to delay in starting the new M4 production lines and a reluctance to let the plant lie idle. By July 1943 1,948 vehicles, plus 84 artillery observation post (OP) vehicles, had been completed.

      The official Canadian history of the war compares the Ram to the Ross rifle as examples of unsuccessful Canadian weapon designs. It states that given the Sherman's superiority, in retrospect it would probably have been better for the United States to produce more tanks, and for Canada to have focused on manufacturing more transport vehicles such as the successful Canadian Military Pattern truck designs. The Sexton Mk I self-propelled gun based on the Ram chassis, however, was very successful.

Combat history:
      As built, the Ram was never used in combat as a tank, but for crew training in Great Britain up to mid 1944.

      The Ram Observation Post vehicles (Ram OP),  flamethrower (Ram Badger), armoured Personnel Carrier (Ram Kangaroo) , Gun armored tower, and armoured ammunition carrier of the Ram saw considerable active service in North West Europe.
Ram OP after landing  This photo shows a Ram OP tank somewhere in Normandy;
 It was a Ram II which had a dummy gun in place on the exterior, and two No. 19 Wireless sets inside.
These tanks accompanied the Sexton S.P. gun regiments as mobile observation posts for their FOOs,
who up until this time had a fairly high attrition rate when travelling on foot or by carrier with the infantry.

   These tanks were mainly rebuilt by Canadian Army workshops in the United Kingdom. Conversions of Ram tanks with the Wasp II flamethrower gear were used by the 5th Canadian Armoured Brigade in the Netherlands in 1945.
     In 1945 the Royal Netherlands Army got permission from the Canadian government to take possession for free of all Ram tanks in army dumps on Dutch territory. Those not already converted into Kangaroos were used to equip the 1st and 2nd Tank Battalion (1e en 2e Bataljon Vechtwagens), the very first Dutch tank units. These had a nominal organic strength of 53 each. However it proved to be impossible to ready enough tanks to attain this strength because the vehicles were in a very poor state of maintenance. In 1947 the UK provided 44 Ram tanks from its stocks, that were in a better condition. Forty of these had been rebuilt with the British 75 mm gun; four were OP/Command vehicles with a dummy gun. This brought the operational total for that year to just 73, including two Mark Is. In 1950 only fifty of these were listed as present. The Ram tanks (together with the Sherman tanks of the three other tank battalions, in part simply taken without permission) were replaced by Centurion tanks leased by the U.S. Government in 1952. Some Ram tanks were used in the 1950s as static pillboxes in the IJssel Line, their hulls dug in and embedded within two feet of concrete.

The kits:  
      Well...this is a long history... Years, many years ago I bought a Ram tank from S-Models, a resin kit.

       At that time, it was the only option to build a Ram. Well: I decided to make molds silicone and merge some hulls and turrets. Good times with the smell of the polyurethane eroding your lungs ...
      The years was passed and I forgot those things in an old box in the back of my closet ... One day, I bought a Ram OP from Formations, build the kit and loved the experience. I wrote to the Formations and bought another, in order to try to turn the OP version in a version with gun. But once again, the thing was forgotten because of more new and interesting projects...Until now !!!

      That's what I found when I opened a box entitled "Ram Project":
Three-dimensional translation of madness !!!!
      I know the S-Models kit is a real junk, with serious dimensional problems and wrong detail.
But:
  •  As I don't have Ram gun tanks in my collection...
  •  As I have a lot of scrap parts available...
  •  As I have time (I'm on vacation)...
  •  and modeling for me is fun, not religion,..
  • I'll try to turn this bunch of resin parts into 3 tanks that may not be accurate for purist eyes, but I'll enjoy myself enough. I guarantee that !!!
      And in the end, I think I'll have at least three Rams recognizable !!!
      Some scandalous parts in resin:
This is Sparta !!!!
       First of all, transforming a Mk II S-Models in Mk I Panzerserra's Models.... I used an spare mantlet from MiniArt to do this:
The hull, turret and tranny are copies...Metal gun from RBModels
Side view. The details in the turret's pistol ports has deteriorated...
Rear view. Notice the rear panel of chassis: Dragon spare part
Dimensional comparison between the hulls:
The upper hull from S-Models are too wide and too short
... but the difference is not that big.
Los 3 amigos |!!!
       As I said before, the details in the turret's pistol ports has deteriorated...I decided to remove the old pistol ports and replace the parts by parts Tamiya
Surgery time: Dremel, dental drill and old Tamiya part
Surgery done...Now, it's time to glue the new pistol port with cyanoacrylate...
The Rams in production line...
Notice the absence of horseshoe in the late mantlet
MkI, Mk II early and Mk II late (left from right)
Metal guns are RBModels and AFV spare part (Churchill)
Brownings for the girls !!!
      And the Canadian Girls, growing and growing...
Ram Mk I - 90% ready...
Notice the absence of fenders, characteristic of the first units ...
Ram Mk II early - almost there ...85%
Notice the holes for the 4 pairs of footman's loops welded directly to the hull
in the rear deck
Ram Mk II late - with shoes, by Jove !!!  Almost 95% ready...

      But now, the Horror; Tracks WE-210 from Bronco (#AB3543), LBL, for the Mk I early. The kit of tracks is very well done, but are thousands of little parts glued on each other, like a real nightmare. But the Ram Mk I used this tracks and the pain is beginning...
Like a toothache !!!
I already told to you: I hate LBL tracks!
Devil's invention!!!
      After a week in this tracks...
Definitely, I hate tracks LBL !!!!
      I finally managed to finish the kits: First of all, the Mk I:
Notice the absence of the fenders and  in the headlights in brackets over the tracks.
Something common with the early models,  like the picture below:

      The Mk II early:

      and the Mk II late:

      When we put the tanks together, we noticed the discrepancies between the models S-Models and Formations.
      But as I said before, the cool thing is that I now have 03 Rams in my collection. They may not be perfect, but are representative ...
      Colors :
      Next step: markings. As usual, I tried to do drawings just like references for decal's application:
  • For Mk I, I choose a vehicle from the 5th Canadian Armoured Division:
  • For Mk II early, a tank from 1st Canadian Armoured Brigade
  • And for the Mk II late, a tank from 2nd Canadian Army Tank Brigade

      Panzerserra decals:
       And the Canadian girls with make-up. Now, they will rest for a night, for the decals adhere perfectly with the Future ...
Notice the glossy aspect: Future.
      And only now I noticed that I forgot to change the wheels from Tamiya suspensions. The Lees and Grants Tamiya comes with wheel bogie with six spokes and holes, which is a mistake. And my kits deserve at least a little more care... Can be built with old parts, but not so wrong ... Surgery time: cut the old wrong wheels from bogies arms:
Notice the arms without the wheels...
      And the girls with right shoes and starting the weathering...First of all, the Mk I:



      Now, the Mk II early:


      The Mk II late did not have to go through corrective surgery: She was born with the correct stamped wheels.


      Now, it's time to paint and built the tools and stowage in the girls...The end is near !!! But, before that, I'll post here the building of Ram OP, that I built in 2004. The kit is from Formations:
The Formation parts...excelent !!!

      And some details in the tanks:


Well, tankers...The final pics... Let's go, Canada !!!!

      Well, lads ... I know the S-Models kits are dimensionally questionable, but the discrepancies are not that big. And while there is nothing better on the market, the Armoured Forces of Canada are well represented in my collection.
See you soon, Boys !!!
