I received these two cases the other day and opened one up tonight. Factory 61, 1969 dated, and copper-washed case and bullet. I might have to order some more. This is the first Chinese 7.62x39 that I've purchased in over 20 years. I've not seen this tin and wire-opener style before.
The other crate markings were painted over and not visible.
Lid off. Note the two "D" handles for pulling the wire openers.
I didn't realize both ends needed to be pulled at the same time.
How the handles should have been used.
