Rich:

I think you are spot on.

It's a little odd that Don Stilson did not provide attribution for the B-42 Twin pictured in the book.

This later design was much better and when Danny visited he made some modifications to mine to stabalize it. 

He also went home with my second B-42 and probably has the only one in Europe.  One was enough for me; although, I would like to have both versions.
