Just remembered: Belle and Sebastian (black and white French thing about a boy and his big dog) and Robinson Crusoe (another dubbed one). How about too Skippy, Lassie, The Lone Ranger, Casey Jones, Zorro, Hong Kong Phooey I could go on...
Yeah, the Banana Splits also had a cartoon about the Three Musketeers. The car one, was it called 'Microcar'?
Also the summer was a time when Flash Gordon or Buck Rogers (the old ones with Buster Crabbe) would get an airing. Plus Tarzan (Johnny Wiesmuller?), White Horses, The Flashing Blade...
