Wespe - 10.5 cm leFH 18/2 auf GII - Sd.Kfz. 124 and ammo carrier version (Munitionsschlepper Wespe) - case report

Freunde ...

     Today's article focuses on this small self-propelled howitzer, which was widely used from the middle of WWII, until the end, by the Germans. Meet the Wespe 10.5 cm leFH 18/2 auf GII - Sd.Kfz. 124:

   The Sd.Kfz. 124 Wespe (German for "Wasp"), also known as Leichte Feldhaubitze 18/2 auf Fahrgestell Panzerkampfwagen II (Sf.) ("Light field howitzer 18 on Panzer II chassis (self-propelled)"), is a German self-propelled gun developed and used during the Second World War. It was based on a modified Panzer II chassis.

     During the Battle of France in 1940 it became apparent that the intermediate tank of the German forces, the Panzer II, was unsuitable as a main battle tank. Though mechanically sound, it was both under-gunned and under-armoured. The chassis, however, proved serviceable for providing mobility to the 10.5cm field howitzer. Existing chassis were converted to self-propelled artillery vehicles, such as the Marder II conversion providing mobility to the PaK 40/7.5 cm anti-tank gun.

    The design for the Wespe was produced by Alkett, based on the Panzer II Ausf. F chassis. Alkett had earlier worked with Alfred Becker to convert captured French armoured vehicles into self-propelled artillery carriers. Among other modifications the Panzer II's engine was moved forward and the chassis slightly lengthened to accommodate the rear-mounted 10.5 cm leFH 18 howitzer.

    The superstructure was lightly armored, with 10 mm armor plate (enough to stop small arms fire) left open at the top and rear. The vehicles were produced by FAMO's Ursus plant in Warsaw.

   The Wespe was in production from February 1943 until June 1944, when Soviet forces approached the frontier.

Combat history:
    The Wespe first saw combat in 1943 on the Eastern Front. It proved very successful, and Hitler ordered all Panzer II chassis production be dedicated to the Wespe alone, at the expense of other projects, including the Marder II self-propelled anti-tank gun.

    The vehicles were allocated to the armored artillery battalions (Panzerartillerie Abteilungen) of Panzer divisions along with heavier Hummel self-propelled artillery. The Wespe brought greater mobility to the artillery formations of the panzer divisions.

   The Wespe proved relative reliability and poor performance, but sorely needed. Like contemporary self propelled guns such as the British Sexton 25pdr. SPG and U.S. M7 Priest 105mm SPG, had inadequate overhead gun crew protection. The Wespe was a considerably smaller target than either of these allied vehicles, but it also held less ammunition given it was based on a smaller chassis chosen based upon availability given limited production capacity for larger ones.

   The main deficiences observed in the Wespe were:
  1. The engine was too weak. Therefore, the Wespe are to slow (only one-third of the convoy speed of a motorized towed artillery). Concentrated movement of a Batterie was not possible because of continuous mechanical failures. The Wespe moved individually.
  2. The Wespe final drives frequently broke down while attempting to steer through the tight curves in the mountains.
  3. Due to overtaxing caused by the terrain, damage continuously occurred to the brakes, brake linings, and their rivets. As an example, because of these problems, only 11 out of 18 Wespe were still operational in the 3.Panzer-Grenadier-Division although this division first came into action with these vehicles for only several weeks. In the 26.Panzer-Division only two out of twelve Wespe still remained operational after four weeks in action. Three Wespe had to be blown up by the troops after they broke down during a retreat. These losses due to mechanical breakdown are especially high when one compares them to only two losses occurring due to enemy action. 
  4. The lack of room for carrying anything in addition to the crew and ammunition in the Wespe fighting compartment is bothersome. It isn't possible to carry along the necessary baggage for the crew such as blankets, washing kits, ration pouches, and cooking utensils. To try to compensate for this limitation in the amount of ammunition, the ammo-carrier version was a constant company of the armed version.

     In spite of several minor weaknesses, the Wespe have proven to be successful on the Eastern Front. The Wespe has proven to be an excellent weapon on the Eastern Front.

The kits:
     Another commission project, using the very good kit from Tamiya German self-propelled howitzer Wespe Sd.Kfz 124 (#35200) for the armed version.
German self-propelled howitzer Wespe Sd.Kfz 124 - Tamiya box art (#35200)
      For the ammo carrier version, I'll use a kit that I bought as scrap, from a colleague... An incredible Alan Sd.Kfz. 124 Wespe (#005), with missing pieces and a very rough construction.
Sd.Kfz.124 Wespe - Alan box art (#005)

      Starting by the scrap-kit (Wespe ammo carrier) ... See how it got my hands: a very rustic construction, with a thick layer of paint and with the exhaust muffler missing ...
Ouch...tons of fun in this case....

The painting is sooo crude!!

But where's the muffler???
      The former owner started converting the Alan kit in to Wespe ammo carrier, but he must have based himself on the art of a 1/72 ACE kit, because it is the only justification for the frontal shield to be curved. All the photos I've found so far of Wespe ammo carrier feature the flat front shield.
ACE kit box art: notice the front shield curved, similar to the gun shield
The drawing, in detail...

     It seems that ACE relied on this photo to make the art of its kit box. But the frontal shield is clearly flat, and not curved (red arrow) ... I think the vertical line (see the point in the double blue arrow) led them to the error of deducing that the frontal plate was the result of the union between the two curved shields of the howitzer ...

Much better!!
     But back to Alan's crude kit: I decided to blast the kit, with a bath of brake oil (2 hours). With an old toothbrush, I brushed the surface of the kit, with the paint coming out in pieces ... After a good wash in running water, I put the kit in another bath this time with lye for another hour. the rest of the paint was blown off and I washed the kit with plenty of running water ... I was almost forgetting to mention that I neutralized the extreme alkalinity of the soda with an acid bath (90% water and 10% vinegar) for 10 minutes. After a lot of running water, what was left was this: All the paint removed, showing Alan's kit in all its glory !! (Oh my God!)
Holy cow!! I think the kit with the painting, the thing was not so ugly ...

The cracks, gaps and imperfections are huge!!

Is there a Doctor on board ???
      Well..let's turn the Alan-crap kit in something not so horrible ... I removed the curved front armor from the tractor and replaced it with something more realistic: the flat armor...And starting the Tamiya SPG.
The ugly and the beauty!!

Tamiya kits are really a delight to build ... 10.5cm Howitzer.

And the upper hull fits like a glove in the chassis...

I discovered some spare parts of Wespe Tamiya in my unbelievable and almost infinite box of spare parts.
Here is a touch of beauty in the monstrosity ....

Alan kits are really crude ... but they are so much fun !!!
      I researched on the internet, in books, under the rocks, I consulted mediums, astrologers, gurus and the Gods and nothing to find a photo of the interior of the Wespe ammo carrier...
      But as the old wise scholar said: "It is better not to do it than to do it wrong ...", I decided to make a canvas cover to hide the inside horrors of this kit. But never forget that I wanted to reproduce what appears in the photos: the Wespe ammo carrier with the canvas cover in place !!

I decided to detail the canvas with reinforcement seams and "trim the girl's braids" ...

I think she is getting almost decent!  Cute!!
      Continuing the building, we must now waterproof and "reinforce" the tracing paper layer, to avoid accidents and stains in the painting (the paper is hydrophilic). I make a mixture of water (30%) and PVA glue (70%) and apply it with a wide, soft brush ...
Appearance of the paper after applying a mixture of water (30%) and PVA glue (70%) ...

The tracing paper immediately crinkles and presents several wrinkles on its surface.
Don't worry ... it's like that ...

But an hour later ...

The surface stretches when the paper dries ...
The paper is waterproofed, more resistant and smoother ...
Primer Tamiya

Ready for cammo and markings..
      And as always, I try to locate the armored vehicles in the historical period, researching the units and theaters of operations that the girls used ... and making profiles as a guide for paintings and markings ... The girls fought in Italy, under the markings of the 24th Panzer Division (Wermacht), the so-called Leaping Horseman Division.

      Well, dark yellow in shades and layers... Old school!!
