Dixon Arkansas oilstone made in Germany.

In bottom half of a wooden box.     Extremely fine feel, fells the same all the way around.  

Box measures 4 1/4" by 1 3/4" deep and 5/8" high.     Stone itself measures 3 1/2" by 1" and 1/2" high.

Box is beat up, but intact.   Bottom of the stone has a chip on it.     Feels like some remnant of a sticker or something on the bottom.

 I haven't cleaned this or done anything to it, I don't know if the gray color can come off.     Very flat, I can't see any dips from repetitive use.
