Just like the made in the motherland variations of AKs, with the rare exception there is really no such thing as a bad Eastern European Communist Steel Magazine no matter the stamp or lack there of. Stamps really come down the individual value based on aesthetics or rarity and have little to do with function.All 3 of mine have an "02" and a "D" stamped on them. The D is clear on all 3 (that's what she said), and the 02 is crisp on 2 of them. The 02 on the third is there but very difficult to see.
I've heard of the "02", but is that good?
