I think most of the small arms came out of Russia. We had Chinese SKS's and AK's ( my own SKS bringback was Chinese), but the WWII stuff was certainly Russian. Most looked beat and had bad bores. Corrosive ammo and no cleaning, ever. I never saw a single 8mm round, so no idea why all of the German
Kar98's. They French
left a pile behind, but no ammo. One VC ambush site I got to, had French 7.5mm cases all around. So somebody had a French rifle. Lots of small arms just everywhere.
