I believe that was a patented "marital aide" that had to be outlawed in 1928.
HIGHLY valuable by collectors in the black market.  (I read that somewhere)

(are you selling?)

Speaking of bakelite; I recently bid on a combo harmonica and player piano;
you put in little rolls about 1 1/2" long and turn a tiny crank while you blow into it.  Very cool, but hard to get an even tune because you have to catch your breath.  (Wish I could remembver the name now)

what is that?

Looks to me like an early transformer

And very well insulated terminals

well i could make out
WESTON CURRENT TRANSFORMER
and
US DEPT OF NAVY, CLASS

so i would guess at it being something to do with radio or maybe radar from the fourties or fifties

Hey Gerhed, I have a Weston meter, maybe a little bit older than your CT. Its in a wooden case, mirror scale, 2.5/5, leather strap. I think they would work well together.

Kevin,

I actually have some slightly older Weston stuff myself.

It is a current transformer. So by passing any cable or wire through the round opening, you can detect how much current is flowing through that wire by non-contact... Simple technique that is stilled used in one form or another today were you do not want to use or can not use a shunt resistor.

I thought it should be something like that, but the fact that you couldn't open the transformer confused me. In a clamp meter you can always open the clamp so you don't have to break the circuit open.

Before magnetics were improved as well as compensation and amplification added to the current sensors to allow for the "clamping" design, all the current meters of this build required the wire to be passed through. You either installed semi permanently or just removed the wire in questions from a terminal and ran it through the gauge.
