I see by the logo that is an International Harvester Co. wrench. These came with farm tractors in the 20s and 30s. Models with the names "Regular" F-20, F-14, 15-30, think cast iron and steel wheels. Probably the only other tools on the farm were under the seat of the Model T Ford, this wrench HAD to do the job, if it fit it had to tighten or loosen the nut. Even if it meant using a cheater or having the fifteen year old son jump up and down on the handle. It is amazing its only bent a little. I look at that as a badge of usage from a far different time than this. Got the one I saved from the tool box on my fathers Regular.
