I used to have a 1916 colt (officer) m1911 that my uncle gave me (stolen out of my car sadly when i was in my 20s), but considering that this is ww2 and not ww1 it wouldnt have been a colt(or shouldnt, if we are going with the more produced 1911) remington stamps on the left of the receiver, and then the government on the right. Either way i think you guys are doing a fantastic job, was just food for thought. (and actually now looking closer at your image i appologize, it does look like you have it as a remington)
Also, looking at your tiger, your cuppola. It would have been a later model (the Ausf E) germany realised from combat in africa and the eastern front the cuppola sat to high (otto carius talks about it alot in his book Tigers in the mud) and they lowered it. Those would have been the ones in normandy (and if im not mistaken, the unit would have been the 503rd heavy tank battalion, otto carius also commanded jagdtigers in normandy with the 512th).
