Anyone have an idea what this is?

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?

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.

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.
