I called the CL guy and it turns out I've known him for years.

We're playing phone tag, so I still don't have any more info about the picture he posted with the CL ad.

And the eBay Thebis went for almost $1,100 including shipping!!!!!!!

Despite the Mrs. hints, I'm keeping mine! I may be opening a bike shop soon and it makes a great conversation piece. (even if it is a piece o. s. from a "practical" standpoint)

Interesting conveyance, but I'd rather ride my Greenspeed.
