I only saw two Saturn Sixes ever. One, with Johnny's United Shows in the mid 70s, which was colored the same as the one in the RAS photos...White Tower with pale green and yellow trim. However, JUSs Saturn Six had "cars" that were white with pale green bottoms. The RAS "cars" were all yellow, I believe.
The only other Saturn Six I saw...well it had to be one of the most unfortunate choice of colors I have ever seen. It was on Drew Expo's midway and it was painted brown and orange. Only saw that one once, probably around '78, give or take a year.
I've never been "with it", just been an interested observer of carnivals for more than 50 years.
Johnny's United Shows..."A Family Tradition" and "All for Fun, Fun for All".
The carnival of my youth, which had roots that originated in my hometown.
