Jib and All!
The first modern attempt at reproducing the Big Base motor was by Lyle Landstrom: http://virtualindian.org/projbb.htm
I seem to remember the project was subsequently assumed (or pirated?) by somebody on the Left Coast, with poor results.
At Davenport this year, I caught wind of yet another attempt to produce improved cases.
It would be great if the Host of this forum would premier their long-awaited cylinders!
