There is a schaublin type 53 universal mill for sale locally. In a cabinet beside the machine I found parts for the machine and this attachment. The paint is very similar. I think it is some sort of rotary attachment to cut helical gears, but I am guessing. There is a universal shaft with a keyed extension as if to allow this attachment to be mounted on a moving table where the power source driving the shaft is fixed. There is a gearbox that turns a spindle with a triangular hole - it is a rounded triangle like a wankle piston - I know there is a name for that shape but I don't recall. The other part is some sort of center support, like the center opposite a dividing head. The mounting surface has a dowel pin and a slot for a key to align with slots on a table and it is scraped. Does anybody know if this is for that mill, or for that matter what it is? If I could find a picture of it in operation I could tell if other parts in that cabinet went with it. Any help appreciated.
