I'm not sure what this came from but it seems like it could have been from a campground or a national forest.   Or it might have just been hanging on someone's outhouses.  I believe it to be Walnut given that it's heavy for its size. Hand made with chisel marks.  See last picture for marks.  Great condition with beveled sides.  13 " x 5. 

would be lots of fun in the den and she shed.  Would make a nice wedding gift or anniversary or housewarming.
