I have no idea what these are... I found them together in a box inside a crate of small antiques and tools that I am selling for a recently retired and moved away friend. I put photos up on a very active Facebook antiques group page and asked for insight; and got NOTHING in return... Clearly, they screw into something and then the handles turn to do something... Grind something? As part of an old record player? Those were my first thoughts... All markings pictured; just the JORDAN you see on the arm of each piece... Each piece measures about 4-7/8" long (including the screw)... Please see pics for other observable details. Please let me know if you have any questions BEFORE bidding.  See pics for condition. This is the exact item the winning bidder will receive. USED... Each exhibits some paint chipping and lots of scratching. Handles turn as they should; with one a bit looser than the other. One has some light corrosion on the handle arm. BUYER pays $7.50 for packing and shipping. NO RETURNS OR GUARANTEES.
