I once owned a 1913 vintage Fox Sterlingworth ejector that was sent to Savage sometime while Savage operated from their Chicopee Falls address. While in their possession, Savage apparently re-blued the barrels, lengthened chambers to 2 3/4", and rolled-stamped the company name and address atop the left barrel. Like you, I thought Savage had done a barrel replacement; but one day while admiring the old gal I noticed something a bit odd atop the right barrel, turned out what I saw were tiny remaining traces of the words "Sterlingworth Fluid Compressed Steel". During the re-blue, most of the original lettering had been carded off; but not all traces were removed. In the interim, I had already received a letter and learned there was nothing on the original production card to indicate this gun had been to Savage (the barrels on my gun checked to letter specs). Maybe the barrels on your gun are orginal also, as it seems workers at Savage may not have been as attentive to detail as original Fox workers.
