I also have a NOS of that hub. I built it into a 20" wheel and put it on an Eska folder with only front brake, with a Schlumpf Speed Drive giving 4 evenly-spaced gears spanning 224%, with no cable to the back.
I rode this bike to work a few times but quickly became disenchanted with the whole bike. A big flaw is that the bottom bracket is too low and on one trip would typically have 5-6 pedal strikes! I didn't install clipless pedals as I could not build up confidence with kick-back braking with clipless pedals. Seems to me a recipe for horizontal trackstanding.
The gearing wasn't too easy to get used to either. So I have since taken the Schlumpf off again and put it on the Yeah. The Eska is going on the block soon.
