Where would the serial numbers be located on a 1923 Colt SAA? I sold a 1923 colt saa and the buyer is saying that it isn’t matching. Last I remember it was matching and for sure had a matching serial number on the cylinder. I told him I would check into it and get back to him. He mentioned the loading gate was not matching but I know this shouldn’t because it’s an assembly number. He also said the trigger guard and backstrap were not numbered at all. Would this be correct for a Colt SAA of this era? Last I recall they did have numbers there but I have to take his word that there aren’t because I don’t have the gun in front of me.
