4 point socket for a brace

[Neals]

I was asked what who where on this one ( Its not mine) Iv'e never seen anything like it and can find nothing online. Any ideas? It has an E on one side and 7333E on the opposite side.

It's what you said, a square socket for a brace. The "E" in a circle is Eberhard Mfg. Co's logo. 7333E is their catalog number.

Thanks Bus!

Technically it's a lag screw driver.

Here's a scan form the listing in Eberhard's No. 9, 1922 Catalog
Number on your socket is probably7388E.

A handle adaptor...hmm...now that's interesting...

Many thanks Bus! You are right on the numbers. Hard to read through all the paint.
