I have two guns which may be examples of the extremes in factory rework marks. One is a .32 RP in nickle. It was built in the 192o's and went back to the factory post WWII for rework. It has a new cylinder, new barrel, and a new nickle finish. It also has a star on the barrel, on the rear face of the cylinder, in the yoke recess in the frame, on the yoke, and on the front of the grip frame, and the date stamp on the left side of the grip frame. The top of the frame was also milled to match the wider front sight of the post war barrel. The other gun is a NM#3, .32-44 Target that went back in June of 1956 and looks new. It apparently got new nickle, new bluing on the sights and barrel latch, new case hardening on the hammer, trigger and trigger guard, and new hard rubber grips, but it doesn't have a star anywhere. It does have a date stamp on the left grip frame.
