I'm working on the Fall Wrenching News Wrench Auction (El Dorado, KS Oct 24 & 25, 2014) and found a box of these wire clamps or crimpers from the wire tool collection of the King Herrington (Aurora, Colorado) Estate. So far I have cataloged over 20 of them. Markings include Western Union Telegraph Co, Dickie, Smith & Hemenway, Bell System, Peck, Stow & Wilcox, M. Klein & Sons, M. Klein & Son and several unmarked examples.
Photos of all the wrenches I ahve cataloged so far are at:
