Very, very nicely done. I haven't hunted ducks in nearly 30 years, and never had conditions to do so that would be nice enough to use a gun as beautiful as that. There was always a Lab or Chessie trying to stand on, knock down or lift a leg on a gun, if you know what I mean. Boat rash happens to things inside a boat, too.
Do enjoy. That stock is beautiful.

Best,
Ted
