I notice it has a U.S. Property mark on the frame. Model of 1911 instead of gov't model?Hello 118artist welcome to the forum. You have what looks like a pretty nice old 1911 gov't model. Please post this in the Colt Semi Auto Pistols section of the forum with many more pictures.
We have a lot of 1911 experts here that can offer their assistance in valuing your gun. I'm sure we also have many members here that may be interested in buying it.
You will get a fair valuation of the pistol here on the forum.
Also, not knowing how much firearms experience you have, with the magazines out of the gun also rack the slide back and make sure there is not a live round in the chamber.Not knowing how much firearms experience you have, the first thing you should do is unload those magazines. If you take it around to any shops or anywhere else, you don't want to have loaded mags with you if you should happen to get stopped by the police for any reason. I can't make out the serial number to date it, but it looks like you have a WWI era 1911 with period magazines and a holster that could be WWI or WWII. From what I've seen around here, $1500-$2000.
