I just got this 22" Avedis and I'm not really able to identify the stamp. The Z and Co are not as deeply pressed as on my trans stamp hats, but it doesn't look like the typical late 50s stamp either:

The bell has several irregular spots close to the bridge. Based on the lathing, I'm pretty sure these are original and not dents.

The bottom lathing is very irregular, varies between wide and narrow with lots of steps:

Thanks in advance!
