The questions are regarding markings.
First, I believe that a star stamped on the barrel of a rifle meant that there was rust in the bore. I've seen the star stamped on some revolver barrels. Did it mean the same thing?
Second, No one seems too sure as to what the "AF" refers to when it is found on Inglis Hi Powers. Some say "Altered Factory", while others say "At Fault". Does anyone know for certain? Thanks, Jim
