Need help please. My uncle has a a Colt that has a 7.5" barrel no rust or pitting, wood grips, no finish. He say's it looks like bare steel. It came with what he describes as an OD green metal box that slides together. Inside is a letter on US Coast Guard letter head that say's something like "here is a good example of a Colt for your collection" It was addressed to a Lee St. Claire and signed by C.H. Gardiner . My Uncle says he remembers his Grandfather told him it was in the family before Oklahoma was a state. As you can tell from the above I have never seen the pistol just a description my Uncle gave me. Thank you.
