I'm helping a friend whose husband just passed. He has a couple of old colt revolvers that she will sell once probate is settled. Does anyone know of a website that will give me general values on these? One appears to be maybe a 1909 US Army marked 45 Colt. The other appears to be maybe a 1907 Brisbey in 41 Colt. The serial numbers are legible, and I will get those today. Thanks in advance for your help.
