Yoshi Konno's brother ran a shop named Cherubium which is where the name came from, I believe. I'm not sure if he even wielded the torch though. That said, anything Y. Konno touched is of some value in the C&V market. Just how much though is debatable. My guess would be that the track frames are probably more sought after due to the feeding frenzy and inflation of the last few years. The track frames were fetching between $750-$1200 on the various NJS blogs. I feel like I've seen various complete 3Rensho road bikes in excellent condition sell for around $1000.
