That must be Les Fruh's variation on the theme, Ray assumed this in post #918 at page 37. He had posted the two pictures from the 1965 Toledo show. I assume Les Fruh tried a different vertical tail because Ed Kazmirski told his own pusher version had too little rudder effect, as expected.

As to the Flop (which was indeed called Taurus in the 1962 MAN annual, #2195 p. 88), we had dimensions from this picture in #1178 p. 48. (Cees had more in his own thread, from the annual picture posted by Ray.)
