You know, just from the fotos, that 9mm Dreiling may have originated @ Heinrich Krieghoff or Sempert & Krieghoff.

Just a followup. Turns out this drilling shoots .358 gas check and jacketed bullets perfectly. I simply run a case to the base of the neck into a 35 Whelen die and it works perfectly. Technically, it is functionally a 9x72R.
I also feel stupid. I was cleaning it last night, and noticed the barrel under the fore end near the latch was marked with a large script Merco. Mystery as to builder is solved.
