I was looking at this CHE 28 ga. Pugs Guns has listed today. If you look at the full size pictures you can see what looks like pencil marks laying out the checkering patter high up on the wrist. You can see it in the top most point of the checkeringby the opening lever. It's on both sides but more so on the right side. It could be my imagination, but it would be amazing if something like that lasted to this day!
Pretty neat gun all around, I'm not positive but it looks like a high flat rib to me!!
