Default What is this vintage object?

What is this strange device? A friend acquired it from an electrical waste recycling place. A test set for telegraph linemen? The cylindrical object looks like ferrite, inserted into a coil.
Ideas?

I believe it is an electrical shocking device, like the old Victorian medical devices.

As you move in the ferrite rod ? the inductance will increase giving a stronger shock.

What's attached to the leads tucked away at front left?

I think that the object in the 1st picture to the top right hand corner is an 'interrupter' or buzzer that makes and breaks the electrical circuit to the coil.

Adrian

p.s. I wonder if a battery was meant to fit in the hole and two leads to handles meant to be held went in the two RHS terminals.

Sorry for the Ebay reference, but it is very similar to item number 175314679506.

It also looks very similar to one of those in my collection.

The leads disappearing into the square hole are connected to a 6V battery pack (4 x AA).

Presumably they are for the battery...

... that Adrian correctly surmises would be stored in the hole.

I can confirm this to be the case.

Interesting!!!. The only job I was ever fired from ON the spot mind you, was my total refusal to make ECT generators. Basically a 400 watt valve amp type mains transformer giving 350 volts DC at about 1 Amp. My refusal was to make the cmos controlled switching so that the number of pulses could be varied as well as the amount of power delivered. I STILL think it was nasty sadists toy.

Well, thank you all very much for answering this query so promptly and thoroughly. The object’s new owner has promised not to test it out on unsuspecting relatives!

This thread can now be closed.

Thanks
