Unmarked wrench ID

[handmadeMI]

I scored a couple sets of these wrenches in an auction. Usa made but no brand name. Looking over alloy artifacts I could find similar looking ones but nothing that is a certain match. Hoping one of the GJ wizards can enlighten me.

The shape brings Indestro to mind.

Looks like the wrenches I bought from JC Whitney in the '60s

The shape of the depression in those wrenches was trademarked by Indestro, I believe.

Indestro or Western Auto. I have a Clip set of these. The heads also are unmistakable.

Indestro. The "Streamline" side panels (with the "dart-shaped" ends) were trademarked in 1937 (TM 346439)
