I just posted this thread from my phone. I got on my computer to see how the pics looked and noticed the thread right before this one is almost exactly the same thing. What are the odds?!If this cymbal is of the same vintage, no need to go into details already covered on that thread.Thanks,Wes
The stamp on yours is the 1.5" tall version of the 1960s stamp (60s tall) rather then the 60s short in that other thread. I picked that up from the quirks in the way it is pressed in, but that's not as accurate as just measuring the height. Since you also measured yours that confirms a 1.5" 60s Tall Stamp. This doesn't make a difference to expected value, but I do try and distinguish them for research purposes because there is a theory about the 1.5" tall version being later 60s. This theory predicts certain correlations with other cymbal attributes.
And yes that weight is unusually high but not impossible. The top five weights I've got recorded in my database are: 2680g, 2720g, 2740g, 2786g, 3134g. Some of my highest recorded weights might also be kitchen scale or similar weights, and sometimes I pick up errors in converting pounds and ounces to grams (when people give both). Once I've got enough weights for a particular production era, model, and diameter, I can start to trim out exceptional weights (statistical outliers) when I do statistical modelling.
