It could work. By that stage of the War, some Germans were abandoning equipment pretty regularly. Then again, if they only went to the Elite (read SS) troops, then it might limit the probability. Still, the maini guidlines for this group build did leave open the possibility of a 'fictitious' subject, since it states:
"4. doesnt have to be historically accurate??????????????"
I'd say go for it. And if there is some historical accuracy to it, I think I'll also look into getting one and building it that way!
