I picked this up off a gun show table because it was shiny, cheap, and interesting (a perfect trifecta!). I have no idea what it is, when or who made it or what it’s used for. Any ideas?
The bottom is marked “52” and 11 1/2”. The rim diameter of the bottom cutout is .61”, the edge ahead of it is .538”. The overall length of the tool is 3.275”.
