Colt Officers Model Match revolver. These have a 6 inch barrel, micro adjustable sights. Best I can tell this is the 1953-1969 5th Officer's Model Match "Colt Officer's Model Match". My best guess of manufacture date is 1966. It has the large Colt grips with the silver medallion. The weapon is in 38 special. No rust and a action that is smoother than butter. I have been told they only made 500 but I HAVE NOT VERIFIED this statement. Just not one you see or shoot everyday. Price is $700. I will listen to trades but do not expect much as I am trying to thin the pile for a move in the future.
