A couple of points confuse me. Is this a 5 screw model? Also, a "K" frame? The pre-war .357's were "N" frames. Also I believe the shortest barrel lenght was 3 1/2 inches, althought someone could have trimmed it further. I agree though that is sounds like a pre-war .357, and the reg #, seems to bear this out, as they also had a special registration # along with the regular serial number. This number was on a special certificate issued with the revolver.
COMPROMISE IS NOT AN OPTION!
