I remember the Unicanitor saddle. It was quite popular for awhile in the 70s. Also remember the Ideal from way back when. And the saddle with a sewup tire in back held on by a toestrap - I did that myself for a long time, but the toe strap tended to wear the sidewalls of the tire unless you put a sock around it first.

Thanks for sharing the site. That was a fun trip down memory lane. And to many places not in my memory.
