The Officers Model Match was an exceptionally fine revolver, intended for bullseye match shooting. The later Python was largely based on it. It was made from 1952 through 1969 or thereabouts. Until 1955 when the Python was introduced it was Colt's top-of-the-line revolver at a time when they could afford to be lavish with skilled hand labor. They're are no economy shotcuts in this gun, it's first-class all the way. I would expect someone who knew what it was might go up to around $300.00 or so, but you might not get this at a local gunshop. Nowdays everyone wants an automatic or a Magnum. You might consider putting it up for auction on a site like http://www.armsbid.com
