I have some pictures of the gun below. It came out of Manton's shop in Calcutta. The gun weighs 7 3/4 lbs with the stock being 4 1/8" through the wrist. I like them that small but it isn't doesn't seem like much wood for that level of recoil. Is there a point where SAAMI standards chganged for the 3" load? It is currently listed at between 19,000 psi and 20,500 psi.

HERE is a link to the maker's website. It has Janssen Freres Fabricants L' Armes Liege on the top rib.
