Had it for a few years, bought it from a small local used drum shop.

Here's what I do know about it:

22".

3450ish grams.

Very flat bell.

It very faintly has "ME-0 Heavy" written on it, not sure if that means anything.

It has the zildjian stamp, says made in America.

And that's pretty much all I know about it, I've tried looking it up a bunch of times and can't seem to find it anywhere online

It plays a very unique sound too, sounds like what you would hear in jazz
