A friend of mine found a old electronic device, does anyone have a clue what this is? and what was it used for?

 

Lift the black plat up off of the box and send a photo of the insides. Also look for any plaques, names,, patent numbers, etc.

 

Looking at the individual items, clockwise from top left:
4-legged thing with wire - not sure.
Top-centre, (caged item) - possible solenoid coil winding, used in conjunction with;
Top-right - spring contact.
Right-centre - Single Pole Single Throw switch.
Lower-right - Single Pole Double Throw switch.
Centre - Potentiometer.
Lower left - 4 position switch.

What it was used for? I have no idea.

 

What type of potentiometer do you think this would be? era what would I look up?

An old megger?

 

Violet-Ray quack medical device?

Self-oscillating induction coil and rheostat?

 

Scientology E-Meter?

crystal radio?

I posted the photo to asked in Taiwan's forum, and someone also saying that could be crystal radio, the time was before your post about 30 minutes.

What do all of those different tags say?

I read one that says, "to carbon at third coil" is that correct?

 

Does the coil appear to be electro-mechanical.......maybe rotate top left device? Is there a core inside coil?

 

as close as we can figure it is a military HAM radio from 1910.
the coil is fixed nothing moves on it.

we are thinking a signal corp radio or a BC 13 a or 14 or something similar.

You're probably somewhere in the right direction.

Could also be a vibrator type spark transmitter.

 

I also thought it is some sort of antique medical device.

The nearest I could find is here.

 

It looks like an old milli volt pot that pre dates some of the early L&N models. I just don't see a galvanometer on it. The center looks to be a carbon pot of sorts with a wiper. Whatever it is, it is interesting.

Gopher, wasn't it you that came across an old L&N version?

Yes, it is still sitting under my workbench if anybody wants it. I was looking for a voltage reference when I asked the .OP to show us what was under the plate - my mind was going in the same direction as yours, Ron.
