Is this a Ford accessory?
Hard to say. It doesn't match anything I have.
It looks like it would fit in place of the fan arm. Maybe for a Ford powered boat that has only a waterpump.
Possibly a piece of one of the "inside the car" hand starters. ???? Im like Jay, it does not match anything I have ..
It's for sealing envelopes and applying postage stamps...You place your right hand on the top knob and your left hand on the curved metal bracket and then push down firmly as you roll it over an envelope or postage stamp.
It looks like my knee replacement.
