Great finding, it is just great info.
I find it comic the part about the Jews. I'm jew, (by family no much practicing), and I take a shower everyday, lol. So no a dirty jew.
It is my understanding that you have being involve on manufacturing some sets designs. Is it really too dificult to carve a Dubrovnik?
I found the recording of Bobby Fischer's 1999 interview for the Philippine AM Sports Radio station discussing his favourite chess set. I transcribed his answer to a question from a listener from Mongolia:
"Where can you get the chess set like the one you used in the 1992 match with Spassky or the one that I've seen in your photos analyzing?"
Of course, it's a Dubrovnik. Full transcript on my blog, took me ages:
