It could possibly be a mid 50s Large Stamp in which case a ruler will tell you because those are almost 2 inches tall.

I find the late 50s small stamp and the mid 50s Large stamp without the 3 dots are the tricky ones to tell apart if you don't measure them. Others may have better diagnostics than I do for that.

Did you find my site? And were you using it for your ids? If so, clearly I need to do some more work to make identification details easier for those unfamiliar with identifying trademarks.

Excellent, i owned many Canadian Zildjians and the had the "made in Canada" stamp. This one doesn't have it.
