I thought Algar might have been a dealer at that time. But when I checked their website it says 45 years which would be 1966. I believe that Al Garthwaitte and Luigi Chinetti partnered as the Eastern distributor for Ferrari for a couple of decades before Ferrari bought it from them. And wasn't Harrah the Western distributor?
In the early 60s Ferrari really did not produce many cars. Chinetti might have been "the" guy that far back. At least on the right side of this country.
