I sent Mobile Tradition an email this morning and got this back this afternoon!

I gave them the colour of the car and the chassis number. 

Dear Mr Hill,
Thank you for your email.
The BMW 2000 rhd Automatic was manufactured on December 2nd, 1971 and delivered on April 25th, 1972 to the importer BMW Concessionaires G.B. Ltd. The original colour was Chamonix, paint code 085.

Unfortunately there are no details about interior and special options mentioned in the delivery books. Maybe you are lucky and able to find the so called "Laufzettel" ('Production note'. PH) under the rear seat bench (where the colours and options are coded). Then you can send me a picture of the "Laufzettel" and I will check the options lists for more information.

We hope this information is helpful for you.

Yours sincerely,
