Thanks for all the posted pics and info; great to learn more about my project. So inspired by Jan's pics of his awesome red example I found a pair of Monoplaner brakes for my project for only $75. Now my decision is between: Polished NR cranks (which came out awesome) and NR calipers with the round, not pointed nuts...or the very cool stock Mistral cranks with the neat and rarely-seen Mono brakes...

And thanks again, you guys are a FOUNT of knowledge.
