B68-365 UNIVERSAL JOINT BRACE. Derlon Patent. Patented in 1892 and with a very high gizmocity rating. This is the oldest version, cast iron without nickel plating or japanning, with a knob rather than vertical handle, a simple iron tube for the grip, and with an open socket rather than a chuck; marked only "Patent." They're fairly crude and look handmade but enough have been found to indicate that it was the first manufactured version. All Derlons are uncommon; this version is very rare. Metal has light surface oxidation, some dings and staining on knob; works smoothly. From the collection of Jim and Christa Schoenky. Good 200-400
