Mr. Petrov did not say that Kornbrath made shotguns. I have read and reread what he wrote and he did not say that Kornbrath made shotguns.I once read that August Pachmayr's journeyman piece was made by him in its entirety,including the engraving. Seems strange that an engraver would have to make the entire gun in order to be a journeyman engraver if that is all he wanted to be or apprenticed for.I do not have a profound knowledge of how the German guild system worked however.Someone enlighten me with a translation of the German rules for apprentice whatevers,surely they must be written down somewhere.
