7302-251 WALDEN patented buggy wrench. Patented July 20, 1909 by F.E. Walden of Worcester, MA. The ratchet action is generated by the end of a spring steel rod which also forms the handle and frame of the wrench. Produced in a range of sizes, with hex and square openings, for use directly as a ratchet wrench, or as the ratchet handle for a ratchet and socket set. The supplemental handle shown on the second page of the patent drawings may never have been produced. This example has 3/4" square opening. A nice clean example. Good+ (NPO115) 60-120
