I've seen a fair amount of Rasch guns. There is no doubt that he aquired actions from other makers, but I've seen enough similarity between guns to think that he or someone working for him finished them. Braunschweig is the town in Germany where he operated from the late 1800's till early 1900's. I'm missing my files, don't remember the last observed date. He was also considered a 'Hofbuchsenmacher' which roughly translates to 'gunmaker to the king' I believe. Most of the guns I have seen are pretty nice, or were at some time. Truth is, there is little known about many of the smaller makers.
