Yup,
IIRC, that was my older brother and my beater bike to get around the campus in college in WI back in the early 80's.
Thing weighed a ton, rattled like crazy and was kinda ugly with it's metallic green paint, Grab-On covered bars and white plastic tie type cable guides, ashtabula crank, hideous looking quilted vinyl covered plastic saddle........but it was reliable and never even threw off its chain on us. It could never kill us when we fell off it as it was so slow anyway. No one ever bothered to steal it when it was parked outside of the buildings during classes protected by a chintzy little chain lock from K-Mart. So we never had an excuse to be late to our classes.....
Thank you Free Spirit, where ever you are now (Probably rusting quietly in my brother's basement or attic in WI....).
