A few weeks ago picked up an OM 45 4 5/8 (1972) with a Ruger brass frame. Since the 45-175xx serial number fell right in the range of the factory brassies I called Ruger first thing Monday morning but no luck. Although the gun letters as a convertible (no extra cylinder with it), the brass frame was not shipped with the gun from the factory. I have had a few brass frames but this is the first factory brassie and the first attached to a gun.
