These 1/12 size military action figure weapons are unmarked. Set includes machine gun with folding stock, knife in sheath, and German or Russian style hand grenade.  There are in mint condition, but unmarked.  We found with a GI Joe vintage collection but suspect these are from the 1980s and could be reproduction Joe, 21st Century, or other.  All in all a very nice fun set for military action figure collectors.  If you know more about the manufacturer on these items, please send details and I will update the information.
