This Czech box, Frank? A 10 rd blue box is also found as well as heavy ball in a tan cardboard box. All Czech made.I've run a ton of East German 54R. Headstamp dates in the late 60s and early 70s and none packed in cans like that. Mine was all packed more like the Czech stuff at 780rds per case in 20rd boxes. I think all of it was LPs though there may have been some lead core too. While I don't have it sitting handy I think it may have been czech made. I'll dig up a box and post some pics.
East Germany did “make” (load and package) their 125gr FMJ flat base steel core training ammo. Always shows up in Hungarian, Polish, etc cartridge cases though. For my own education...I would have to open that tin up. Gots to know!!Looks like the tin used the USSR before the green spam cans came out. The stuff that the little triangle boxes came in. Also looks just like the Polish tins of the 1950's. The blue box def. has the Czech look to it though. As Ammolab said, no documentation of any 54r made in the GDR. They made x39, 8mm, 8mm kurz, but never seen any GDR made 54r.
You pull on that folded tab in the upper left corner of the OPs photo. This tears off the whole left side of the lid. Then you can tear off the rest by grabbing that opening.If that can has circular pull tabs on the strips to pull it open, I'd wager it is a Czechoslovakian-mfr. batch...
Personally, I'd open it too! Of course, then I'd have to shoot it at the range as well!
If my memory is right the EGerman training Ammo wasn’t packed in a tin. As it was range ammo to be used on in country military base ranges, the expense of weatherproof secure packaging was not needed. The Czech training ammo also forgave the tin inside the wood case for a tar paper wrapping.I have a tan/yellowish box of the ZV, headstamped ZV 65.
I ordered a bunch of the East German 123gr short range ammo in the 90's, if I remember right it came in a pinkish wrap or boxes in a clear plastic flat that prob came out of a tin. Good ammo with low recoil. Loose EG round with ZV box and charger.
