Hi Maser
The car has lived for the last few years in a private museum/collection in the north of England. The collection is a privately owned family affair and they (the family) have decided to concentrate on veteran cars and so are disposing of the 60's 70's cars in order to rationalise the collection.
The car's chassis number is not known by Bonhams (lord knows why) though they quote it in their on-line catalogue!
It has no MOT and has not had for some years.
The condition (body/chrome) of the car is 6.5 out of 10 'at best'.
The car cannot be started/tested/driven before the auction.
The car cannot be put on a ramp/jacked up before the auction.
Bonhams will give NO assurance as to the mechanical condition of the car, and do not know when it was last run.
Bonhams will not guarantee the mileage (nor will they tell you what it is - you'll have to go to see it).
The car is available for viewing at RAF Museum Hendon on Sunday from 10am to 5pm. The man in charge is Tim Schofield - head of Department at Bonhams - (very helpful - he's the source of ALL of the information in this message.
I get the impression that the car has been standing unused for some years so it will need re-commisioning.
Hope that helps, but the bottom line is that whoever buys it will be throwing dice to some extent.
Regards
Mark-Anthony
