This is not the one that was discussed on Cymbalholic a while back, but a recent example. To me this cymbal look fake even at first glance, but not everybody will probably be able to tell from the look alone. This was sent to me by a guy in Italy who wanted to get my opinion about it. The seller is claiming it to be 25 years old.
If you look at the trademark it superficially resembles a new stamp. But there are several problems with the stamp the greatest of which is that it says Zilojian, instead of Zildjian. Also there's no signature under the bell.
