I have a Bosphorus 20" Masters ride- very thin at around 1575 grams. No issues- definite patina-logos mostly taken off. Drilled for 2 rivets. Sounds trashy and delicate. Let me know if you're interested.
I have a very nice thin 20" Bosphorus Masters ride. No nicks, cracks or dents but plenty of stick marks. No rivet holes. Logo may be fading a bit- will look at it tonight. Let me know if you are still looking.
