This is probably not a T tool. What is it?
My left front paw shows the size. The cup with the square hole swivels, slightly. There are 3 seperate 90 degree bent pieces mounted loosely at one end. The handle is T shaped, viewed from the end. The only markings that I can see, before a thorough cleaning are M34 on the back side of the socket. Any ideas what it might be? Thanks.
It looks live an old valve wrench. On the back of fuel delivery trucks there is a spring loaded valve where you hook the drop hose when delivering gas to a service station. The square hole slides on the lever, you press down to open the valve and use the tab on the end to lock it open. They are still similar today.
A fuel tanker valve wrench is exactly what that thing is. There are variations including some that have a curved handle with a bend on the end to tighten hose fittings. One I have has WHEATON cast into it.
