Its a compressor for supplying a very large instrument.
mather & platt brush lifters with shorting ring.You were right the first time! It IS a starter, but why is it like it is? What's in the bottom box that operates the rheostat? Here's a picture of the motor, not sure that tells you very much but it's a 12hp Crompton Parkinson wound-rotor induction. If you only had a fixed rotor resistance instead of a nice 10-stud starter, you could pull the lever on the end to throw a shorting plug into the slipring connections once up to speed. But for this application it would take longer to get up to speed on a fixed resistance and anyhow there's no-one around up here to pull the lever. The man who just hit the start button is down in the pit getting ready to begin.

No idea, but a bargain for £6!
