Maybe an electric fence controller ?

Hot wire with a door bell transformer....

See if you can make out what connections are positive and negative and hook up a battery and cables.
Move the lever and see what happens.

It's definitely a high amperage switch of some type. Id say it was a transformer inside but i only see one coil. If its meant for high amperage, I suppose it could have some old version of a built in relay inside and that would explain the coil. You can clearly see the inputs / outputs on the side of the box. It could've been used for something like turning lights off at an old ball field. It does kind of look like a Door bell transformer like Stefen said but id see no reason for a huge turn off switch like that.

Looks like a crystal radio set with coil in the box and fine tuning outside.

Correction to an earlier post:
To me, this looks like high voltage, but low current - NOT high current.
High current devices would never have exposed terminals like that, and would require MUCH larger wires.

My guess is this is an electric fence on/off control switch, as mojjax has already suggested.
The year 1933 is really too late to be anything related to telegraphs or spark-gap transmitters, plus, the apparatus doesn't appear to have the required connections for a keyer.

Erze82 - be careful if you decide to power this thing up.
Think: Touching a 9-volt battery to your tounge, only (probably) a lot stronger!

We have several electric fence controllers . They all have 3 terminals on the outside of the box . 2 go to the fence , 1 goes to a ground rod .

On off switch for sure could be for just about anything.

At 1st glance I thought there is a plunger inside the coil making it a solinoid/knocker.
But if the outside lever moves the plunger/actuator in & out of the coil, then i'd say a tuning coil of some type.

Looks like some type of rheostat control box? HH

Here's an early electric fencer from google patents -

Looks like someone gutted a crank telephone to go "fishing".

Agreed. model train probably

Good call! I think you're correct about that. If it is an electric fence switch, i suppose we don't want to be killing people hah!
