Offset Reverse Gear Wrench for Model T Ford with 5/8 and 11/16 openings. This wrench was designed for adjusting the reverse and brake bands on the Model T Ford, and the shank is offset at the 11/16 end to provide better access. The wrench measures 8 1/2" long and is in good used shape showing some rust and pitting from use and age. I do not see any maker mark on this
