My lgs has a 1911 that if anyone here is well off they need to come buy it asap. I would if I had the money. It is a 1911 Colt .45 US Navy model. Is still has the U.S.N. tag on the lanyard loop. He says it was made in the year 1911. I did take down the serial number to verify. He is asking $5500. What is the book value on this pistol?
