Randy, thank you for your help. It’s much appreciated. I will try to get a copy of Swayze’s book. My squareback is a 2nd model based on serial number...
Prowbar, it certainly is possible. What makes you think it may be a repro cylinder? I have wondered if it might be a 2nd generation Colt? Thank you....
Randy what is the condition of the cylinder safety pins on your squarebacks? Is it possible for the pins to be in very good condition if the gun did...
