I am looking to buy what is labled as a Colt 1917 in 45 ACP. The serial number on the frame and yoke are the same 237XXX. On the frame there is a symbol or letter(s) that I can only guess are a "B" "H" or "E"??? The butt is marked as follows: U.S. Army Model 1917 No 85502. The right side of the barrel is marked as Colt's Mfg Co Hartford CT USA and the left side is marked as New Service 45 Colt. The dealer admitted that is has been reblued and the stocks looks as they have been replaced as they are checkered wood with no medallions. Also the lanyard ring is missing. He is listing for sale at $590. I do not think that this is worth the price and I am not convinced as to what the correct caliber should be. The rifling looks good and the action seems tight. Any help would be greatly appreciated. Thanks.
