Yeah, probably a tough one!

Thanks for any info!

Indeed. Others will have more wisdom than i, as i only go by interwebs' info for dating, and it seems they are one of a number of places which lost serial number records due to fires? (been a while since i looked.) and my impression is i've mostly seen pre great war or 70s-80s with a modern or two thrown in here or there, so clear zipper seams in the centurians, and not that i can recall in young ones.

So that set of data points does not narrow it down at all...

I'll closely look over my 60's an 70's era Cervenys a bit later, but I can tell you I owned 80's era cervenys from 1988 to 2023, and I never noiticed a zipper seam on the bottom bow
