I have seen photos of the car. It is a little worse for wear. The interior is tired and there is a fair amount of rust in the air vent panel under the windscreen. I would say, verging on terminal. It is only running on three cylinders a the moment, but that could be anything.
It looks like a 65 model, slide style speedo etc.
The seller doesn't know much about the car and he is selling it on behalf of a charitable organisation... Nice guy though and he was most obliging to my queries.
Unfortunately Mike (Tippett), the vehicle is not with him so no body number. ID plate is one of the small Heidleberg type, not the black and silver of the later models.
It would be good for spares, if you had an early resto etc...
