Take a look at list member (on hiatus) Rick Chasteen's Schwinn stiff gear.

It's been described as Darth Vader-like. Black Maverick seems like a good name for it.
I ridden it a couple of times and it is a pleasure.
The Schwinn cantilever frame production goes back to 1938. I wonder if Henry Meyer and the 30's Schwinn team ever got a wild hair to set up something like this.
