Can you identify this tool?

[SideShow]

I was told this was an early Ford engine tool (of sorts), but unsure of its specific use. Can anyone identify this tool?

No Idea! But i'll take a guess and say side window removal tool

Looks like the one end chucks into a brace? For turning something?

Maybe for a valve grinder?

Something like this:
