What is this?

I think it's a bead breaker too. I thought of that last night, and find two confirming posts here this morning. I would imagine the rebar triangle base would be driven over... no. The tire would be off the vehicle and lying flat on the ground with the axis pointing straight upward and the tread touching the vertical post. Then the breaker bar with the spoonish tool tip would be adjusted to the most vertical position possible/necessary and placed on the sidewall of the tire nearest the rim as close to the bead as possible. Then the operator would be able to lean downward on the long lever and exert a great deal of force concentrated near the bead....

That makes sense. Now I just need to drag it up to the nearest antique dealer. Thanks guys.

Quite correct.
