I have several variations of these in my Victory model collection. They are, as said above, conversions from the Pre-Victory & Victory Model WW2 era revolvers, usually done by the British gun companies from surplus guns sold by the military after WW2. The pictured gun appears to have been refinished at least once and rebarreled, so it's value is limited to shooter value, or as an oddity. Most of the conversion done in England have adjustable rear target sights added. Ed.
