Joe Wagner designed the Chief, which I think is classic eligible. He also designed the Super Chief which predates his design of the Veco Chief. This was flown in 1950, so it is OTS eligible. I have a set of plans by Joe Wagner showing both designs with copious notes. Apparently, the Super Chief was flown by George Aldridge, and it influenced the Nobler design. Joe Wagner also designed the Dakota biplane. The Super Chief kit is available from Brodak.
