Do you know this chess set?

It is a roly poly chess set, but nobody could tell me when or where they were manufactured.

broomstuck, I discovered that offer, too, many years ago! Absolutely love it. What is the reason you believe it is a copy from Schmitthenner's? There is a link to a video in the article description on etsy, where you can see the pieces bow and rise

@ungewichtet I have no proof that it is made in the former Soviet Union but the pieces are not of the same quality as original Smitthenners set. Especially the knights carving is much inferior (which also applies to the set from the OP).

Here some pics of an original Staunton variant made by Schmitthenner.

And the set that matches the drawings of Schmitthenners patent application:
