Franz Umfahrer is another possible source for Ferlacher tubes:
>>Franz Umfahrer, weapons and barrel maker of Klagenfurt, Kärnthon may have been a little larger regarding craftsmen with around 160 craftsmen but his hydropower was at 14 Pfdkr. His operation had 4 barrel forges( Laufschweissfeuer), 2 tube hammers, 4 barrel boring machines and 3 lathes. He founded his quaint business in 1853 and twenty years later it had really increased as he claims in 1872/1873 to have supplied around 7000 components to Austria, Egypt, Germany, Italy, Modlan Walchei(?) and Russia in that year or in total by that year which I'm more apt to believe(He advertises as supplying makers in the whole of Austria(Oesterreich), in Deutschland, Italien Russland, Egypten, in der T�rkei, Moldau und Walachei, by employing some 160+ craftsmen). He may have finished the barrels<<.
