RARE 1884 ELLRICH PATENT RATCHETING SCREWDRIVER SET IOB

Rosewood handle and complete with the four original drivers in their box. Two tabs on the side of the handle one with 'L' and the other 'R'. Not sure how this functions and the tabs may need some lube as they don't seem to move but I have not owned one of these before to know. Good clean condition otherwise noting one tip is chipped.
