Archer Self Propelled 17 pdr Valentine Mk I - case report

Tankers!!
      I always liked the low, stylish and aggressive lines of this tank destroyer: the Archer Self Propelled Gun 17 pdr Valentine Mk I. 

Archer Self Propelled 17 pdr Valentine Mk I
      Nowadays, it is very easy to build one of these beasts: just buy the excellent kit of Bronco and have fun.
Bronco´s Archer kit (#35074)
      But when I built this project (2005), the only economically viable option for my possessions was an obscure kit from Maquette, that I bought pretty cheap on eBay. Oh my God .... As I regretted it !!!
Maquette kit (#3552): horrible!!!
      I'll show to you guys a project that almost border the madness and the insanity. IMHO, the Maquette kit that I used was the worst kit ever made!!! Let's laugh (and suffer ...) a bit!! But, first of all, a little of history, as usual.

History:
      The Archer Self Propelled 17pdr, Valentine, Mk I, was a British self propelled anti-tank gun of the Second World War based on the Valentine infantry tank chassis fitted with an Ordnance QF 17 pounder anti-tank gun.

      The Archer was the second in a series of self-propelled guns produced on the Valentine chassis. The first design produced was the Ordnance QF 25-pdr on Carrier Valentine 25-pdr Mk 1, better known as the “Bishop”. The second design was the Self Propelled 17pdr, Valentine, Mk I “Archer”. The Archer is not quite the expedient hack job that the Bishop is nor is it nearly as bad as the hack job of adding a 6-pdr gun and gunshield to the top of the Valentine in place of a turret. The Archer was reasonably well thought out.

      Rather than develop a new vehicle from scratch, one of the cheapest, lowest and more reliable chassis was chosen, from the Valentine infantry tank. On this base, to avoid the gun clogging in every obstacles encountered, Vickers engineers chose to place the gun in a reverse configuration. The gun was pointing backwards, contrary to the direction of vehicle travel.
      In other words, Archer moves with the gun pointing back. When approaching your shooting position, she turns around and stands on his sniper position using the reverse gear.
       Once done the shot, if there is a need to escape, she is already directed towards to escape route, running from the shooting point without turning or reversing.
   This way, the only possible tactical use of the Archers was for defensive or ambush purposes. Look the picture below:  The direction of displacement of the vehicle is the yellow arrow Notice the faces of the crew: they are looking to forward, except the man sitting on the gun, looking back at the camera.

      The driver and commander were seated in the front part of the casemate, which had a hinged armored flap and vision slit. The casemate was open-top, multi-faceted, sloped at the front, sides and rear. The rear part was open, in order to allow the gun shield some traverse (11°) and elevation (-7.5 to +15°).

Notice the gun angle and the amount of ammo in the ground:

      The 17 pounder anti-tank gun was a very powerful gun but also very large, heavy, and could only be moved about the battlefield by a vehicle, which made the gun more effective in defence than in the attack.

      A version of the Churchill tank had been tested as a self-propelled gun: the "3-inch Gun Carrier" and the US was expected to be able to provide the M10 GMC Wolverine through Lend-lease.

       Other projects were considered using obsolete tank chassis. Possible vehicles included the Valentine, for its reliability and low profile, and the Crusader, for its good power-to-weight ratio.
     In development were tank designs using the 17-pdr, which led to the A-30 Cruiser Mark VIII Challenger tank (and its post-war variant the Avenger), derived from the Cromwell cruiser tank, and the Sherman Firefly conversion of the Sherman tank.

      The Valentine chassis was soon chosen, as it was in production but obsolescent as a tank in British use, and was also one of the few chassis that could accommodate such a large gun. The engine in the Archer had a higher power rating than in the Valentine. Since the Valentine had a small hull and it was not possible to use a turret, the gun was mounted in a simple, low, open-topped armoured box, very much like the early Panzerjäger German self-propelled guns in appearance, with the gun facing to the rear, which kept the length of the Archer short. The mounting allowed for 11 degrees of traverse to either side, with elevation from -7.5 to +15 degrees.

      On firing, the gun breech recoiled into the driver's position. So, he actually had to leave his seat when the gun fired. He still could stay in the tank, but had to place himself left or right of the breech.

      Because of this, the Archer couldn't fire while moving. But after shooting, the return of the driver to his position was immediate. And the fact that the vehicle already fired from it's back allowed the Archer to evade its ambush position immediately without turning around. The rear mounting gun combined with its low silhouette made the Archer an excellent ambush weapon.

      The first prototype was completed in 1943, with firing trials carried out in April 1943. Vickers were given orders for 800 vehicles.

    Production started in mid-1943 and the Archer entered service in October 1944. It was used in North-West Europe and (in 1945) in Italy. By the end of the war, 655 of them had been produced. The Archer was classified as a self-propelled anti-tank gun and was operated during the war by the Royal Artillery (RA) rather than by Royal Armoured Corps units, as too were the British 3in SP, Wolverine and 17pdr SP. Achilles.

      Post war the  Archer served with the Egyptian Army. Surviving vehicles are preserved at the Yad La-Shiryon museum in Latrun, National War and Resistance Museum, Overloon in the Netherlands, and the The Tank Museum in the UK. The Archer served with some units of the Royal Armoured Corps in the British Army of the Rhine (BAOR) in the early 1950s.

The kit:
      First, I would like to warn readers that the following images are crude and impactful. Modelers with heart problems and children must be careful. Warning done, come on ...
      The kit box:
The worst kit in the World; Maquette Archer Mk I  (#3552)
      And the box contents: a mixture of injected (Valentine) and resin parts that awake desperation and horror screams :
      Sorry about the poor quality of the pics: This kit was built in 2005 and digital cameras at the time were quite rudimentary ...
The Maquette kit: Valentine (badly) injected and resin (awful) parts
Unbelievable...
Maquette's 17 pdr. gun barrel: warped!!!
Thank the gods, I had a metal barrel...
Resin parts were indescribable ...

Trying to use the useless...



Believe it: This is the sight of the gun...


The cradle of the gun ...amazing...
      Now, you might be asking:
1- Why waste time with such trash ???
2- And why post that ???

      Well...
1- I NEEDED have an Archer in my collection ...
2- I wanted to show how happy we are now, with so many choices of (excellent) kits and manufacturers...

      Continuing with the agony:

Gunner's seat
Rear part of the 17 pdr. gun...
trying to turn waste into kit ....
       Now, the best part: the Archer's the superstructure. Cutting instructions of upper hull kit were highly descriptive ....
Oh my God !!! Simple, right ???
Starting the surgery....

Done...
Adding resin parts: notice the perfect setting ...@#X!!*#
      Now the icing on the cake: the sides of the armor in resin were so bad that I decided to do everything in scratch ...I've never seen a casting so bad ...

And the magic moment to throw the leftovers in the garbage !!!
      Now, the best part: Markings. My ungrateful girl will use Canadian clothing. After a good research, I found this photo of a Archer fighting in italy. What caught my attention was the Wizard doll (perhaps the mascot of the vehicle) on the front shield of the vehicle. Bingo !!!

      Well, Gentlemen .... Sorry show this old and strange thing, but I badly wanted an Archer in my collection. I already bought the new Bronco's kit and soon will build it and photograph next to this relic. I'm really very proud of this pretty Canadian girl !!!!

See you soon !!!
