Great find with your initials and all. I would spread fine layer of Tru-Oil on bare spots, and take that thing wildfowling or turkey huntin' using TMatrix or Bismuth. You might want to invest $5 for camo gun sock to cut down on glare though.
Trying to fix things that aint broken can lead to small disasters (lost or damaged screws,.....).
Looking at the screws it seems like it was not taken apart since proof date, so strip clean & "lube" by pro might be in order though. While he/she services the metal you can take that wood and work on it if you want, but be careful what you use because the wrong stuff might swell the wood so it will not mate the metal on re-assembly.
