So make a short story long, there is a contest called the Oregon Manifest to design and fabricate a utility bike. If they have it in 2013 and if I can raise the money, I am going to enter. Any how, in determining the "ideal" geometry for this bike, I looked at what I have. And since it is important to me to visualize, I made drawings.

The black is from the early 1930s, the red is from the late 1950s and the blue is from 2009. The first set of overlaps shows when you align the saddles and bars. The second set of overlaps shows when you aligh the BB.

I find the results to be not very surprising but nonetheless interesting.
