I too suscribe to Steve and Chucks "minimalist" approach to renovation because I think it brings a shotgun back into presentable condition without destroying the collectible value. I think this approach is appropriate when I shotgun is in tatty condition but I also have no problem with a total renovation as described earlier in this thread when the gun is a wreck. While the result will have no collector value at least it's useful life has been extended.
