Brent D, the sleeper in photo 5 does look like it has some nice wood, but it is pretty small and has some sapwood on one side of the front. There is a buttstock in the lot from an old gun that he appears to have been replacing. Here's the blank with some mineral spirits on it (the other side had less sapwood, but I didn't take another picture):
As for the odds and ends, the one I am puzzled by is the stock and forearm. Does anyone recognize this symbol?
