I remember being driven around the high speed test track, in a Grenada powered by a York IDI Transit engine; fitted with a Brown Boveri comprex supercharger.
It was a bit scarey.

When I first started at Rover (Austin Morris at the time) the welding spares stores still had a few Ignitrons (a relative of the mercury arc rectifier), they had to be stored, moved and installed upright as splashing the mercury over the internal connections could ruin them.

True, but you can't transport the bulbs upright as the force of the mercury splashing around will break the glass.
You have to turn them carefully upside down so as to transfer the mercury to the large bulb, avoiding contact with the electrodes.
Spare bulbs were also stored upside down in crates.

Well, you hit the hammer on the nail. That is exactly why I like them. They make an excellent exhibit if they make the visitors feel the same way.
Besides that, they are extremely rare. There are a few in the UK, a couple in Germany, but I am quite sure that we have the only working example of a MAR in Holland.

The MAR's at Kempton are very impressive, along with the appropriate switch gear. Seeing those made my day on the recent visit, a rare sight indeed!

There are one or two in the Milne collection at Amberley but not to be seen working.

Phill.
