    Found this odd curved Proto “Socket” Wrench. Info stamped on it:

    F-1541006(or G?)
    5/8
    Proto Mfg USA
    SAE 50558

    Can’t find anything else like it - possibly custom tool made for a specific purpose? I contacted Proto and they didn’t have any information on it, either. They only said it was called a “curved ratcheting wrench”.

    Anyone else ever seen one like this?

      Look like wrenches used to tighten valves on aircraft?
