Sorry for the late addition...this may help someone identify their damascus barrels maker.
.
In 1894 a British patent was issued to Eugene Joris of Fraipont Belgium, who lists himself as a "manufacturer", seeking a patent for a new metheod of manufacturing damascus tubes. He prefaces his patent by stating that "damascus tubes in use up to the present time consists in rolling the steel band into a spiral".
His new patent damascus is comprised of 16 longutudinal rods, without a mandrel, that can be welded by rolling in a press or by hand hammering.
.
the key info is that another damascus craftsmen has been identified including city of origin..the patent number is 1981, it was issued in 1894....And yes, there were still a few stragglers interested in hand hammering well into the 1890's... NOTE...Not to be confused with Belgian gunmaker Jean Joiris of Wandre Belgium...jor not joir
