So I bought my first EM... a Williams SKYLAB. I've been trying to find a list of rubber sizes for it. I've found plenty of ring kits for sale, but I can never bring myself to by those. I'd measure them, but I am pretty sure many of them have stretched from their original size.
I have plenty of white rubbers in my toolbox, but there are a few that seem really large to me.
If anyone has a list of their sizes, I'd be grateful!
