I am a welder by trade, and on a distant side of my father's family, trace roots to Silesia in your Republic. My father's mother and father immigrated to Ohio from the mining area in Silesia about 1911- they both died in the Spanish Flu outbreak in 1917- dad and his siblings (4) went through the Catholic Church's orphanage system (read that slave labor for area farmers in Ohio) but he was fortunate, as the folks that adopted him lived in Akron, the head of the house was a machinist, his wife a nurse- no children of their own until they took in my dad- One of his sisters, my late aunt Mildred, lived in Masarak Town in Florida, he was a hero to the American Revolutionary War as much as Gen. Pilsudski was-- great history.
I am a forum member on the GGCA gruppen, both Mike "Der Amerikan" and Raimey are very well versed in Deutsch waffen und waffenfabriken--but from my years in the welding and machine shop trade, I specialized in TIG welding of die steels, machined parts in both ferrous and non=ferrous metals, I can tell you that the DeWat style welding of the steel rods into the barrels and also the actions-- almost impossible to repair and make as good as when built-- and all welding processes impact the parent metals with heat, not just in the HAZ (heat affected zone) but throughout the mass of the metal parts and components as well. Welding brings the base metal close to the critical temperature, and with fusion and filler rods, etc- adds to the HAZ, cooling as the weld path progresses- so, in layman's terms, put the barrels on a blacksmiths-forge cherry red, and see the temper fade from the steel as it cools- thatis about what might have happened to your Drilling.
