I was lucky to find a 67 1.3 rally that was sold new in the US. the car is very original but think somethings were changed when it was first bought....
The 1,3HF is in "Le Maggiorate", there's the "1,3HF / 1,6HF" with the die-cut "HF" cover, there's a b&w 1,6HF brochure, and there's a fold-out poster...
My 2c was restored 1997_1999 after sitting for 21 years, with only 27.000 miles on the clock and one previous owner.
All my photos taken at the time...
