Vance, I have a excellent copy of Felix Wankel's original technical paper;
Eintellung der Rotations Kolbenmaschinen presented in 1963 at Technische
Entwicklungsstelle der Fraunhofer-Gesellschaft Lindau/Bodensee.
It is written in German and has dozens if not scores of configurations of 
rotary engines all illustrated in color that Felix considered before he decided
on the rotary configuration we now know and love. It was give to me by 
Eurgen Bax Pres. of Wankel Gmbh when I visited the factory in Korf. Are you 
interested in a copy? The paper is 60 pages with about
20 pages in color. This would add greatly to your presentation on the 
Wankel rotary. You must pay for the copy :-)
