Whiskey, I believe the handgun you're describing is the American Arms Regulator Model. It is actually made by Uberti and began to be imported to the USA in 1992. It is offered in .357 Mag., .44-40, or .45 LC with either a 4.75", 5.5" or 7.5" barrel. This is basically a reproduction of the Colt Peacemaker. It has a brass trigger guard and backstrap, fixed sights, half-cock and hammer block safeties, color case hardened frame and a blued barrel/cylinder and walnut grips. In excellent condition this revolver could be worth about $230-$270 with a premium added for one with a nickel finish. Hope this helps!
