What the hell is this? Bead Breaker?

[Farmall 1066]

Bought this at an old service station auction last fall, thinking it was a bead breaker, but can't seem to figure out how it works.
It's stamped "Wenco Crete Nebraska" on the handle and looks to be factory made.

WAG = snow chain pliers

With the spoons, and piece to grip the rim, I'm leaning toward bead breaker, but not sure.

I'm pretty sure it's for stretching fences. Basically a larger version of the snow chain pliers.

I could see those, maybe, but why the flattened spoon ends on the curved piece?
I also saw some old alignment equipment on this sale with same Wesco name stamped on it.
