A seller listed an "original" Swivo on ebay for many dollars. It IS a cool pedal-- way far out of my league.
But as part of his listing, he has some early magazine ads. Does anyone know a source for those? True, they may be original, but it's easy to download pictures if you can find 'em.
He also has patent drawings, which are available online as well as the Swivo manual -- anyway they were. I've got 'em, and can share!
