I asked the supplier I bought this set from (the one I was looking for in this thread) about, what seemed to me, a replacement pawn. He said it wasn’t and went on to elaborate on the natural variation within old soviet sets, esp. the “Latvian” one. This he said is because each piece was turned one by one, individually. That really is one of the crucial differences. I mean look at this set of pawns! : (supplier photo - I asked about the 2nd full white pawn on the left).
This is absolutely true and an excellent point!
Def check out Etsy and search for "vintage chess sets". Just about every one of the search results will be Soviet-Era! Reasonable prices too!
