Tool ID

[Levaughn]

Hello all. I got this tool today at a Yard Sale. I thought it might be a wobble extension. but am having my doubts. The round end has the numbers 1175-B stamped on it with an "A" on top, and the square end has the numbers 1880-B stamped on it with an "A" on top. I can put a 1/2 inch extension inisde the square opening. If anyone could clear up the mystery it would be appreciated. Thanks in advance.

Looks like an industrial assembly swivel extension of some type.

It could be Apex brand. They make power sockets/extensions. There are a few other brands also, I was just going through some odd power sockets I've collected.

I have a lot of the Apex but nothing with a square end but you could be on to something.
