Concerning wall thickness on Prussian Dalys, I have a very Lindner like J.P. Sauer 26" ten, yes 10, gauge Krupp barrel gun at 6 pounds, 4 ounces empty. The wall thickness is quite adequate in both barrels and the stock is standard dimension and bulk. I have no idea how they built a full size ten gauge at that weight with good wall thickness. I have a good collection of Lindner guns but have always shied away from the Featherweight guns, thinking the barrels were too thin.
