R Marshall,
FW Heym's patent was the first hammerless drilling, a fact they are still very proud of. The Gun was not necessarily made by Heym, note also that they reference the Anson and Deely system, but they didn't make it either. Note the Heym patent included 3 triggers, and 3 hammers(Haemmern) on one pin( axel "Achse"). The use of the word hammer is a little unusual, now they would likely be called "schlag stueck"( hitting or striking piece). If the drilling had 3 triggers, it wouldn't have a selector. I too am concerned about the same thing WBLDON is.
Mike
