At grandpa Russ's 85th birthday he was telling about his old Colt. He thought it was an old cowboy gun, because it was used in the new frontier. Being he said frontier I got thinking of the Frontier Six Shooter was a possibility. He thought it was from late 1800's and came in a old leather covered case. I told him I new just the people to ask. He's going to let me see it the next time we go down. Oh, he was sure it was a .44. Now if I just had the serial number it would be great. He could not believe it when I got that excited about this old gun. I want him to get a letter from Colt, but I thought I'd get some of your thoughts any way. Thanks.
