Interestingly enough (arguably) I seem to recall there’s one of these towards the end of the film “The Train” as a Wehrmacht convoy - including this vehicle - is unsuccessfully flagged down by the German Colonel (Paul Schofield). I think I first saw this film - quite powerful in its own right - as a kiddie (around 10 years old) and even then thinking, “What the hell is that?”. Mind you, it sort of looked the biz being camouflaged and all (I think).
I might get one of these just for the hell of it and see what I can do with it in Wehrmacht finish.
