10 speed automatic

Back in the early to mid 70's I had a Sears 10 speed. It had what looked like a normal 5 speed cassette on the rear but only a single ring on the front. The rear had an internal planetary gear that would shift up when you built up road speed and momentarily stopped pedaling.
As I recall, down shifting was achieved by a short back pedal. It worked great for a quick downshift on small hills.

I put a lot of miles on that bike before I built my first real road bike in 1976. I kept that old bike until I lost it and the rest of my bikes in a fire 4 years ago.

Anyone else familiar with this old bike?

I remember reading the ads in the catalog, and considered it until the Bicentennial Free Spirit came out. Then it was over.
