Moore Drop Forge Hex shaft Speeder Wrench

[Parabellum]

Has anybody heard of a speeder wrench where the cross section of the
tool is hexagonal? I have never seen a hex shaft speeder wrench.
It does say "Moore" on it. I believe it would have to be Moore Drop Forge which also made Craftsman, later became Easco, then Danaher.
Looks 1920s. Has a stamped hexagonal ratchet in the set.

Have I stumbled on a rare find?

I think I have a vintage hex speeder wrench somewhere. I'll look around for it.
