A minimum affordable but representative collection:
German - Kar 98k, P.38, P.08
British - Rifle #1 Mk III, Rifle #4, Enfield .380 revolver
U.S. - M1903A3, M1, M1 Carbine, M1911A1 pistol
Japanese - Type 38 rifle, Type 99 rifle, Type 14 pistol, Type 94 pistol.
Russian - Model 1891 rifle, Tokarev semi-automatic rifle (M38 or M40), Tokarev TT-33 pistol, Nagant revolver
Obviously, this is not all the types of guns used in WW II, but it would be a good representative collection and of considerable pride and interest. I have left out automatic weapons and the more expensive.
