Yeah, and maybe straighten that stamp height thing out. :D
No need for a timeline to do that. I can straighten that out for you right here and now.
Forget about stamp height. The whole secret to identifying cymbals is:
1. primarily the trademrk
2. secondarily the manufacturing characteristics
Trying to identify cymbal eras using trademark height does not uniqely identify anything except the large stamps. And even that only tells you that it falls into one of three of the categories that are uniqely defined by the specific trademark type anyway. And the same goes for bellhole sizes. You'll still see some people trying to rely on that too these days.
At the time I wrote that article I thought trademark height might be helpful, but as it turns out its really not. A lot has been learned in 10 years. You'd be surprised.
