These pics are of the bikes as-found and unwashed.

The Sekai measures out to 57 ctc on the seat tube and 57 ctc on the top tube and has a standover clearance of about 32.5". SunTour components as well that probably added to my confusion. I kind of like the little brake releases up on the hangers. And that handlebar tape is growing on me. I took this bike for a short spin around the block, probably risking my health with the tire condition, but this bike could be a nice commuter and daily rider as it felt and rode nice.
