Guess I'm luckier than you guys. All of the ribs on my guns are sound. I asked the question so that in case I come across a gun for sale with loose ribs I might buy it and do the repairs myself. Years ago I took a 20 Ga. very minty Nitro Special to the gunsmith (Adolph) at Abercrombie's on Wabash St. in Chicago. He did a swell job without relaying ribs or even messing up the blue for $15.00. He was trained in Germany and very skilled in working with double guns --- and would have scoffed at the idea of relaying the ribs. For what it's worth, I tend to agree with SKB: each one is an individual case. That NS must have left the factory that way because it sure had not been used much. Thanks for the input. Chopper
