I have 2 of them and they look identical.  Anyone know who made them & what they were for?

I'll go first.

Lug wrench?

Skip

As skipskip said they look like lug wrenches.

If you google double end lug wrench you will see them. All the ones I have saw are larger and for trucks. You slide your handle into the whole an turn. Some even have a stabilizer bar going to the ground.

We call them wheel braces (or wheel nut sockets/spanners) in the UK - brace because the early one were just that, a steel brace wih a socket at the end - as cars got bigger, so did the wheel nuts and the brace didn't have enough leverage. Detachable 'tommy bars' allowed the tool to be kept in a tool roll. often issued as part of the car's tool-kit.
