This is an Antique 12” Standard Board Werks Steel Monkey Wrench (#2486) I believe that the writing on it states Standard Board Werks. Very hard to read. It weighs 2 lbs. 14 oz. and has a wooden riveted handle. The screw moves the head very easily. I did not clean it, because I don’t know if that lessens the value. I am selling as is and it needs a good cleaning. Pease see pix for a complete description.
