Parker Serial Number Guide

[Brush Buster]

Kevin ,you don't show the entire lug in your picture ,behind the 20 toward the rear of the lug should be another Number as stated earlier it should be an 0 ,1 or possibly a 2 ! That number is your frame size ! Then on the end of the lug you should find the last three digits of your serial # !

Ah, ok! Thanks so much!
Please excuse my lack of knowledge on these firearms. I’ve never acquired any of this caliber, so to speak. My collection consists of handguns and newer rifles/shotguns.
