I need to sell an Ithaca M1911A1 for my late fathers estate and I am pretty handgun ignorant. It is marked "M 1911 A1 US Army". It has these markings: "P" on top of the slide, "P" between the trigger and the handle, "FJA" between the trigger and the handle, "C" on the other side of the gun on the trigger guard(?). I don't know where the serial number is. It has a chrome finish, which I know is not desirable. The gun seems to be in good condition. Any idea how much money I could sell it for? I also have a leather case that hold two extra clips.
