My son Dan scored a 22 inch Type II trans stamp, (based on Drumaholic's research and Zenstat's documentation) which is presumably from around 1949. It weighs in at a very thin 1900 grams! It a very complex sounding cymbal that plays and sounds very differently depending on where you hit it over the entire cymbal, probably as a result of the varying weight distribution. In the sweet spot I identified, this cymbal is dark, woody and awesome.
It just came today. He bought it a few days ago at Steve Maxwell's NYC store and had it shipped. He probably overpaid for it, but it is definitely one sweet cymbal. I will eventually add a sound file.
The Type II stamp, based on Zenstat's documentation, is slightly bigger and has several characteristics which differentiate it from other trans stamps. If I've misspoken or left something out, I'm sure Drumaholic will set me straight. :)
