M43/M47 shoulderboard buttons

[Slobo]

Thanks Toshik, very helpful. I assume that even after 1946, so many rimmed versions had been made and imported that they would still be common well into the 1950s for RKKA and MVD security forces, or am I wrong?

Also, did MVD/Militia and the other security organs go a different route with buttons in 1947+? As I dig into this topic I've recently seen some rank illustrations and references for MVD/militia buttons having just hammer an sickle and not within the RKKA star. They too appear rimless, at least in theory.
