B65-107 BITSTOCK. Darling Patent. Patented by Benjamin Darling of Bridgewater MA in 1868.

A spring is placed in holes along the handle to open and close the jaws. Cast iron construction, 8" sweep. Surface oxidation but no rust or pitting, one of the nicest examples we've seen. From the collection of Jim and Christa Schoenky. Good+ 400-800
