I have about 10 pieces of the .45 ACP and 20 of the 7.62x39. There are no NATO markings and no numbers to indicate year. No markings of any kind. The primer pockets were never crimped and I don't think any sealant was ever applied. I accidentally reloaded a .45 ACP before I realized it's different and it looks like any other piece of decent brass, as in no belt from excessive head expansion due to soft brass. Again, they are Boxer primed and not Berdan. I can't tell if they were originally corrosive primed or not. Nobody else has ever found or used anything similar?
