That one will work!
I like to use an oil finish on my Squirrel calls. Just Teak Oil from Home Depot or Lowes, rubbed in with a few coats, then waxed. It needs to be replenished from time to time, but then, you do clean your rifle now and then too right? Anyway, nice call. I like the classic look and simple no nonsense design that say "I'm a hunting call, let's go hunt together!"
