[COLOR="DarkRed"]Well...I think the Istanbul Pre-Splits (when Agop was alive and the signatures and names of both guys appeared on the cymbals) have already achieved that status.
Some of the early-run Sabians seem to be inching that direction too.....
Ad some of the discontinued Paiste lines are also getting a cult following.
It's a good question and a good subject for a thread...
....very hard to say, because one wonders whether over time the contemporary Turkish handmades (Agop, Mehmet, Bos, Masterwork, etc) will actually start to lose quality or become more standardized or just consumed....and therefore the void will be filled by something else....) Could also happen that one actually goes under (Masterwork being the most likely candidate) which could actually then make 'em collectible in a decade or so.
I can add that Meinl has discontinued a few lines which were VERY good cymbals (the Amuns, for example...handmade, hand-hammered B8's which are just beautiful; also apparently their original Soundcasters have now morphed into 2 separate lines....dunno why they did that, either).
So it could be that something gets discontinued despite the fact that it was a well-made cymbal with a small, loyal following. The Turkish companies seem to be able to weather that sorta thing just fine and not nix good lines...but it seems the bigger a company is, the more likely for them to axe a series if it just doesn't sell to their expectations....regardless of the quality of the cymbal itself.[/COLOR]
