A most interesting vehicle. I've not seen this example before. It appears the rear wheels are individually braced to the chassis frame; I can't see a rear axle. Could you post more pics?
As you likely know, the Allied forces did not take the field with mobile field kitchens, excepting the Russians of course. There were a number of hasty efforts to copy the German example in the early months of the war, and this may have been one of them.
The design is unique to say the least. Avoiding the German practice of articulating the vehicle is bold; though it was almost certainly road bound.
Please, more pictures, and contact our retired French General if you still correspond; I'm sure he can shed more light on the subject.
Further to the above post. The primary "cuisine de campagne" is pictured below. I always suspected it had a rigid frame, but it may have been articulated; I've not seen a surviving example.
A smaller, one horse version, in two variations, was also used, but in far lesser numbers. I assume it was used by mobile units; artillerie, cavalry, etc.
German: SUPPE soup FLEISCH meat = German field kitchen ?!
That was my initial assumption. However, I couldn't match it up with anything German. So what is the next biggest German-speaking population? Correct. Some digging revealed that it's a Swiss Model 1909 Fahrküche. One of 460 built in Thun, Switzerland.
