I have a rifle strikingly similar to it. It has a European walnut stock, a polished but case hardened percussion lock, the trigger must be set to fire the rifle, a brass under-rib, and I re-barreled it years ago with a 7/8" Green Mt. barrel, opening up the channel a little to replace the metric tube. The original had extremely poor rifling, almost like it had two sets of grooves: one straight and the other, twisted. The lock did not have a fly, but I added one as the rifle has single stage set triggers. My daughters both grew up with this rifle and it is a keeper. I have admired that ad all my adult life.
