Does anyone know what this is? Help please!

I recently went to a flee market and bought this. The owner couldn't tell me what it was, so he gave me a good price on it.

On the box says it's a "SHOCK-PROOF CONTROLLER" made in the U.S.A. by the National Electric Instrument Co. Inc. in Elmhurst, Long Island, New York.
I surfed the web but found nothing on it, nor the company. I did find some brochures from the mid 50's that say the Company used to build electrical medical equipment.

Does anyone have any idea about what the item itself is or does? Information about the company?
Do you think it could be worth something?

Thanks in advance!

It looks like it screws into a light socket.

It may be an old time version of a surge protector. Just guessin'.....[huh]

It looks like some kind of doohickey that you can regulate something with like x-ray kvp or something similar.

Yes, it screws into a light socket, and it has a little lever that changes voltages....????

Low voltage power source

It's a low voltage power source for diagnostic instruments. Here's a link to a newer version:

How do you know you got a good price on it if you don't know what it is? lol

Puzzicato has a good point!

That said...what do you intend to do with it?

 

[Bazer]
