Just received the info on # 1114 from the Centro Storico:
According to our documentation files, the chassis number AR 1801114 originally corresponds to an Alfa Romeo 1300 Junior Z (105.93), engine series AR 00530, manufactured on the 28th January 1972 and sold on the 31st August 1972 in Italy.
The body colour is red, with black tex interiors.
It shows how long it took to sell this car, 7 months... but maybe it was a dealer demo or so...
Olaf, the date that I have on your car (June 29, 1972) is that the manufacturing date or date of sale to the first owner?
