British Contract Colt Official Police (mfd. 1941) in 38/200 or 38 S&W with a 5" barrel. The finish isn't commercial grade, but I had the internals checked out by an old-time gunsmith and he advised that it's very clean and in excellent shape. Now all I have to do is get some ammo for it. Colt made approximately19,000 Official Police in 38/200 for England in 1940-1941. In contrast S&W made over 500,000 Military & Police models in the same caliber for England from 1940-1945. I would imagine this is a big reason why the British Contract OP isn't as common. In addition the S&W Victory models were under the Lend-Lease Agreement while England paid for the Colt OP's. This one is still in 38/200. It was not converted to 38 Special. No importer stamp so it came into the states before 1968. It might not look like much, but this old veteran is one of the crown jewels in my modest collection of six-shooters.
