From the pic it looks like it started life as a ride cymbal,it looks like it has a steep profile,and a really long bridge.I have had a couple of early 70's thin 20's and they had a steep profile also,they were so light I thought they were could be crashes but the profile was a lot steeper than my A crashes from the same period.I have heard if you contact UFIP that they are pretty good about trying to answer your question about whether a cymbal is one of theirs or not and when it was made.

Thanks for the advice on contacting UFIP - I did send them an email and got the following answer: "The stamp on the left-hand side, 4 from the bottom, was not owned by UFIP but by the Zanchi company. Well, in fact we can say that it was UFIP, because Zanchi was part of the UFIP company. As you probably know, UFIP was founded in 1931, but from that time until 1968 UFIP was only working as a distribution company for 4 small artisanal foundries existing in the area between Pistoia and Florence. These small foundries were Zanchi-Biasei / Tronci / Marradi-Benti / Rosati and they were used to produce cymbals under many different names for many different customers. Best regards, Alberto Biasei"

So not alot of detail there other than it's possible my cymbal was made in Italy somewhere between 1931 and 1968 by Zanchi. Am still researching to see if I can find out more details. Any other info anyone can share would be appreciated!

How about you keep it, and play it and make some awesome music with it? BTW The Italians made GREAT cymbals, with very, very few exceptions, I think particularly the B20 cymbals made in Italy are, in general, of the same quality as anything made elsewhere. They did make some other alloy cymbals and they're basically on par with those alloy cymbals made elsewhere as well.

My wife and I took a trip to Italy in 06. I had planned on heading over to the UFIP factory since it wasn't too far from Florence, where we had a free day on our schedule. I was hoping to sweet talk the wife into letting me buy a cymbal straight from the factory while we were there.

But then one of the other wives mentioned that the shopping was great down in San Gimignano and there went my free day. Oh, well. It was a nice dream.
