Heller Masterench Adjustable Wrench 10 inch
This is a nice clean example of a Heller Brothers 10" spring loaded, self-adjusting masterwrench (pipe wrench). It has a spring loaded jaw that ajusts to the smaller pipe sizes as presure is applied to the handle. The serated jaws are in very good condition like the rest of the wrench. It's marked "HELLER MADE IN U.S.A. PATENTED 10" MASTERENCH". The trade name sounds like Masterwrench, but the WR is dropped in the actual name. There is also a Heller logo near the name (standing horse). This wrench appears to have been little used, very little wear. A nice clean older wrench, some very minor staining or darkening to the finish, no rust, straight not bent, in very good working order with a strong adjustment spring!
