More Model-C questions and random photos!

Jim C's Model-C

Okay, here is a few more random photos that I just found from the weekend I built up my Model-C. It was fun just dorking around on it and it was even more fun when you realized everything was possible on it. Just a few more questions.

1) If you had to choose 2 top tube lengths to offer which ones would it be?
2) From the sounds of it, you guys aren’t interested in a 21″, would this be correct thought?

Please leave all the answers in the comments section! Thanks again!
