I've been restoring a couple of Swivo one piece footboard pedals. I really like those rascals! An interesting design, fun to work on.
There's a guy selling a 'first generation' Swivo on ebay. He's asking quite a bit of dough, and good luck to him. But he seems to be knowledgable. We've corresponded a bit, about one mystery in particular.
Mine has all the features he describes, e.g. the pedal post hole that goes all the way through, machined parts, etc. But I found something on mine that neither of us know.
First, on the base piece, under the chrome swivel/heel connecter part, mine is stamped "2," and there are three small indentations. They aren't holes, but little 'divots.' His is stamped "1."
And on mine but not his, there is a stud threaded into the center hole in lieu of a threaded collar lug. It doesn't secure the piece, but sits in the 'channel' of the swivel
It's threaded, so I can back it out and put in the lug. But is has the factory installed look -- it's a unique piece.
I'm hoping pictures will explain what I'm trying to.
So... calling on the collective wisdom of the VDF. I'll bet someone is interested in weird little facts too!!
