Wow! Great set and photos. Board too?
I know you discussed refinishing the pieces but I don't think you should (but I think this was your eventual conclusion as well).
Weighting is about personal preference as well. The Dubrovnik chess set from the 1950 chess olympiad was unweighted and this is one of the things Bobby Fischer liked about it. If you play with fast time controls (i.e. bullet or blitz) you want a stable piece... heavy and wide bases are less likely to tip over during a quick game. This set was common in tournaments so I would expect classic time controls where you're not "russian" (lol) to move a piece.
If it's weighted, you will have the inevitable rattling when the piece ages.
Okay, I say “my” chess set, but it’s only temporarily mine until I gift it to my stepson for Christmas. But the set I ordered from a seller from Ukraine came in a few days ago. The listing said “Soviet tournament chess set ‘Zvezda’ 1953 (first grade); Manufacturer: Mordovian Temperature Plant #5”.
Yesterday I took some photographs of the set before I started individually giftwrapping the pieces. I’m quite pleased with how the photos came out, so I want to show them here. It’s such a beautiful set!
I’ve heard that generally, the heavier the chess pieces the better; but I must say, I found these weightless chess pieces very pleasant to handle. I don’t know how they would play, but I was surprised by how nice these light pieces felt. I’ve heard that a set like this tends to be around 300 grams. The knights were kind of curious to hold (but not impractical) due to how much they arch backward. And interesting how fat those rooks are compared to how slender the other pieces are (the large knights notwithstanding). I really like the proportions of this set. It’s not very balanced, but very compelling because of that.
This is my impression as someone who doesn’t play chess, anyway.
