The barn has "Sharp Stuff" on a sign above the door and there is a number in a rectangle in the grass just off the pathway to the barn. Didn't Rick call his business "Sharp Stuff?"
It's Bowles' work. Look a the deer in his gallery on his website. If it was not registered with the shop it would be unsigned. I had this one he did for for Jack Crider... no number, no initials. It's one of the un-etched Shaw Leibowitz Specials.
