What a schmuck-a-della ad- The sellerdoesn't know from Shinola about Fox guns- #2 or 2#-either way- doesn't mean a second barrel set- it is a weight stamp--Fox didn't mark frame size, as did Parker, or have two basic frames per gauge, R and FW, as did LC Smith- but they did mark most of their barrels with a stamped number- 1 through 4- I have two AH Fox shotguns- A 20 gauge Sterlingworth made in Utica in 1933- 28" barrels with a 4# stamp- But my 12 grade B with Krupp Fluid Steel barrels has no weight stamp number-and are an even 29 &1/2" long- full choke in each tube, uncut-Strange!!
I wouldn't go pronouncing Schmuck-ness just yet. The location of the single number 2 (below the serial number) does, in fact indicate that this is a second barrel. The weight stamps on Fox barrels are on the tube itself, immediately ahead of the barrel flats ON EACH TUBE. The weight stamp digit is also always stamped with the number in line with the axis of the bore. The weight stamp is never found on the barrel flats. It is very common to find Fox barrels with no visible weight stamps since the tubes were stamped before they were joined and filed up. Very often the weight stamps were simply obliterated during this process.
