Im curious about this marking on a 1906 navy. The back of the grip is marked WW/5751. When you zoom in at the marking its got some noticeable machine marks in the grooves of the lettering. Is that a common look for these markings? I know they were not put on the gun at the factory I don't think. Im just curious about what one looks like up and close.
