Determining gauge of gun

[David Codding]

Thanks, George, I'll definitely obtain a research letter from PGCA. Love to find out who the original owner was. Still trying to find the stamp saying it's a 10 gauge, though.

A gauge stamp is almost never seen on early Parkers, so you can quit looking. The frame size stamp should be on the bottom of the rear barrel lug. The barrel weight stamp is on the left barrel flat. Are you confusing the weight stamp with the frame size stamp. Of course, at that weight, it is most obviously a large frame. What is your barrel weight stamp?
