It's a Dynator, an alternator in drag. Haven't done the wiring mods yet hence the lack of connections.

I'll post some pics of the 'new' tachometer when it's back from the instrument rehab centre.

Nice work - is that a Lucas C40? Presumably you had to make a bracket up yourself for that?

It's a Dynator shaped like a Lucas C40 tacho drive, as original. The casing is ally instead of the original dynamo's cast iron, so it's not too heavy. The cast pulley/fan is from Sunbeam Alpine. Original cars had a huge pulley, which gave charging issues and really wouldn't work with an alternator. The Alpine one is exactly the same design, in cast aluminium, but a little smaller to aid alternator cooling and charging. With the stock Cobra size an alternator wouldn't charge at idle. Oh, and originals are utterly and completely unobtainable, unless you know someone breaking a Cobra.
I have a dummy RB106 to go with it, which acts as a junction box and cleverly also contains a big full-system fuse.

The bracket came from El Gerrio, who is now making them. And everything lined up!! Had to fab up the adjuster bar, though.
