Back when they were converting Krags to sporting rifles there were a lot that had wood added for a high comb and a pistol grip.

Funny you should mention that. I saw a Krag sporter conversion at a local show today that had been pieced to add both the higher comb and the pistol grip. If I recall correctly, there were at least 4 pieces of wood spliced into the original stock. Very well done, but no way to tell if they were simply glued or had been pinned as well. The seller was asking less than $400 for the rifle and I was tempted, but I'd gone looking for something specific and didn't want to spend the money on anything but my target (Browning Hi-Power, Belgian, 60s era - which I did locate and am considering).
