Cool Higgins, crank addict. Is that a 2x4x3 hybrid transmission? If so, that is an unusual location for the IGH shifter.

I really like the period-correct handlebar-mounted water bottle, as well.
I once had a Sturmey-Archer standard (wide-ratio) 3-speed hub with a 14-16-18-20 Cyclo cogset, but only one ring (40T) in front. Great setup!
