OK, I give up, I enjoy researching stuff a lot. But I give up after 3 hours of searching on this one. Obviously a cutting device, but I don't know what it's supposed to cut. It is marked, with what I believe to be S ELLIOTT NEWTON MASS, which leads me to believe Sterling Elliott, but trying to find a list of just his patents turns out to be a chore, and he holds around 125 patents.
So, somebody out there please tell me what it is so I can sell it intelligently.
Had to edit...it is NEWTON MASS not Boston, my eyes were going buggy trying to read it. This pretty much confirms that it is a Sterling Elliot patent since Newton was his factory hometown.
