I have a Parker GH that has the wood dished out well below the forend iron with no damage to the iron itself except some burnishing. The only thing that I can think that caused that was constant rubbing on the side of a wooden duck boat while the watermen was paddling or tending to decoys or traps. The buttstock is a somewhat crude replacement. If it took the same kind of use(abuse) as the forend I can see why it needed replacing.
