An update from an observant collector who pointed out the barrel underside does not have the usual "UNITED STATES PROPERTY" stamp which might explain the first repair of $5.81 which did not show what was repaired. Being there are only three main components, frame cylinder and barrel. I know the frame wasn't replaced, the cylinder was in the second repair for $7.64 that leaves the barrel at $5.81 first repair? Being a commercial repair/sale they would not have supplied a barrel with "USP" stamped on it. It does have an eagle proof and of course the serial# on the barrel flat.

Does anyone know when the "USP" was applied to the barrels?
