2600 Berlina dates

[George Caracatsanis <gcara@xxxxxxxxx>]

There is some additional evidence that the 2600 Berlina was still available
in 1969.
Quattroruote's yearbook 'Dizionario delle Auto 1970' published in July 1969,
includes the car in the Alfa range, listing its price as Lit 2.600.000
(funny coincidence or 'matching numbers'?).

As a comparison, the 1750 Berlina was listed at Lit 1.865.000.
