Two wires from the rear - grey and grey w/ black (or are they meant to be white? - sorta looks like speaker wire to me though!)
Bulb holder underneath - green and red wires
Yep, that's the one I have.
Could never ID it. Asked a few Instrument repair places, and a few classic car forums, no-one had any idea. Mick's idea of an aftermarket one is a good one.
To hook it up:
The bulb hooks in like any bulb.
The Grey, Grey Black Trace wires go to the coil, in a negative earth car, the G/B wire goes to the the positive, Grey goes to negative.
That's how I hooked it up to mine, Well I think it is, can tell you next week when I'm working on it. (Stored at a friend's house, can't get back till next saturday

)
If you need to know sooner, let me know, I'll see if I can get someone to go check it before then.
These are pics from the inside, just for interest:
