I recently bought several cans of what I thought was 80s Hungarian light ball surplus. However, once I opened the can, I noticed that all the packs were wax paper wrapped late 1940s and early 1950s ammo with a mixture of head stamps. There were 5 different country codes in one pack! I can't figure out why there would be such a mixture in an 80s dated can. Any ideas? Also, can someone help ID the country code "23"? I've looked at several reference sites and can not find it. Other country codes I found were 17, 21, 22, 25 and 60. Dates range from 1948 to 1954. Any info would be appreciated.
Thanks!
