This struck a chord and I had to do the usual searching all over the place for something that I had not seen in years....
I did find my copy of Formula 3, 1964-1966 (1991), the Fact Book that the Formula 1 Register did some years ago. Along with the FJ Fact Books, I bought it thanks to Cliff Haworth being among those campaigning F3 in 1965/66.
