So in the final analysis, the timeline does not need to be revised at all. Just amended with an asterisk for the early types which were not necessarily made when the series was actually first launced. And a double asterisk for hand hammered ones. Anf for those cymbals only their manufacturing characteristics will be the way to separate them from the others, and define them as unique.

That looks like a gem of a Crash Ride. My A&CIE is typical of the era.
