I suspect you have been severely duped. Your set is Chess Antiques' Moscow 1935 Chessmen repainted; I’m pretty confident your set isn’t vintage. I’m adding one of your photos here for reference:
The 1950s to 1960s BFI II sets feature queens with obloid finials, and kings feature peg finials. Note the finials of this 1960s set:
Your set's knights look like the 1935 Moscow Chessmen knights rather than the more panther-like later BFI II; and your kings feature the spike finials, and the queens the more diamond-shaped finials of the Chess Antiques set, which is more of a BFI II interpretation rather than a reproduction.
I think it’s a beautiful set, and I love it even more with the red varnish. But it’s a modern production.
Either that, or your set IS vintage, and Chess Antiques modeled their set onto yours. That would be really fascinating if true. I’ve seen one late BFI II set with replacement flame finials on the kings (like the Mordovian kings), but I’ve never seen an original BFI II featuring queens with diamond finials.
I would love to have a set of the old Soviet chess pieces. Are they weighted? Beautiful, just beautiful.
Most Soviet Grandmaster tournament sets were weighted yes. Here are a few of my different rarer all wooden knight 40's-60's versions ...
Thanks . You're quite right. The early Soviet GM sets are my favorites because of the cool wooden knight variations. Here are the different set knights together for comparison ...
