Thread: Guessing Game Mk III : What Engineering Marvel is this.?

I might be thrown off by the paper and scribe looking thing.
If it has wires it might be a switch of some description. maybe loke a rotary switch, by the looks of the shaft running thru it?

I don't know. I'm just guessing now!

It is sealed and calibrated.

Getting warmer though, it is a bit like a rotary switch.

An early seismograph?

It's from the steam era, and is still in use today, mainly in metropolitan areas of Sydney and Melbourne.

Is it an inline lubricator?

OK...
Steam era- for some reason I'm thinking of the wild west.
Like a rotary switch. If its early, then its electromechanical, relay.
Lots of wires (they don't look like pressure tubes, more like cables with lugs)
Still used today- this has me stumped.

Maybe a signal relay for telegraph repeater station? Not sure if still used in metro areas though!

Very, very close! Think transport.
