This was given to me this weekend. However we are not sure what it exactly is.
My friend said that he was told it was Japanese and that it is for loading machine gun clips.
It is a brass like material. Very thin. On the ends you can see very flimsy ears. Maybe for one time use?
It measures 6.5 inches (16 cm) long and 3 inches (7 cm) wide.
Assuming it is as we are told, it can't be for a type 96 or 99, these had curved clips. Type 100 was small caliber. Maybe type 97?
Anyone want to take a stab?
