I don't know where that gun is now and when they show a picture of it, it seems to be the same old b&W picture. In an early 60's book Fired In Anger there's a long article on how a gun collector bought a standard old nickel Colt .45 in 1962 then later sold it. But he kept the hard rubber grips. Later he took a closer look at them and saw the abbreviation "Bat Maston" scratched inside one grip. "Dodg CY" and various other initials linked to other famous guys were on the other. The grips were sold to the guy who didn't know he owned Bat Masterson's special ordered Colt. One of them, anyway. It was verified by Colt and I think the Kansas historical Society had the letter Masterson wrote requesting the two guns with modifications on a Dodge City Opera House letterhead. Somewhere out there is that other matching Colt. A couple years ago another Masterson Colt was on auction and it was identical but with a 5 1/2" barrel.
