While looking for information on the Kondu Manufacturing Company I found this wrench on Ebay. The seller describes it as a Western Electric 1/2 & 3/4 Open End Wrench part number KONDU-23WX. Measures 8" long. The open ends measure 1-1/8" and 1-5/16", note the curious stepped and round-ended jaws. The wrench is numbered 1/2 and 3/4. My guess is that this wrench might be related to the Kondu company and the 1/2 and 3/4 refers to conduit sizes in inches? Anyone with ideas?
