I should live so long as to shoot an NID, Sterlingworth, Parker or Smith loose with normal home care. We all know that Lefevers never shoot loose, as long as the adjustment screw can be moved. Now I am sure that I can destroy any of them if I abuse them and shoot heavy loads with out any decent care. Shoot the shells they were designed to handle and clean and lube them properly they will last for generations to come.
My gun room has more worn guns than many. All my NIDs are tight. If only these old guns could talk I doubt that they would tell me less than hundreds of thousands of shells have been shot through them collectively and they all still work. The American double was a rugged gun, built to take use and abuse. They last and last far beyond what is reasonable to expect for a gun which most always cost $50.00 or so at the most. Heck of a value if you ask me.
