Notes: "This is a truly gigantic pantograph, with the longest arms a full 38 inches long. The wooden legs are also quite beefy, measuring 23 mm wide by 13 mm thick (15/16” x 1/2”). The pantograph was made for Dietzgen by A. Ott, whose logo and model number can be found on one of the legs (picture 3). This pantograph is what Dietzgen called a suspended pantograph, and originally would have had a cast iron pedestal that carried its weight, rather than resting on the paper. The suspension wires are still in the box. There is no place in the box for the pedestal, so that must have had its own box. In any case, at some point the pedestal and pantograph got separated, and the pantograph itself is all we have here. "
