Need a pipe wrench for your Locomobile ? Evidently they were a little pricy for their 1899-1929 era. $10000 would have bought you a home or a Locomobile in that time frame. I choose the home as did most other people. This wrench was made by Walworth using Stillson patent. Other side stamped Stillsons wrench Pat Aug 1882 Walworth Mfg Co Boston USA. This is 8in wrench.
