I don't know a lot about these guys except that they say they are Turkish cymbals. Does anyone have any more information about this particular cymbal? I haven't seen it, but it's a 20" ride, I only have the one picture.
Thanks.

Just did a Google search and saw another like yours claiming it’s from the 80’s, made in Istanbul with that same style ink stamp. It was called a dark ride and was 20” also. That may be the same but can’t read the worn off ink stamp under the nion in Dominion.
Looks like a cool cymbal. If you try it, let us know.
