Hello Peter, regarding:
<<Are the following statements correct? --- 60's-early 70's French rear derailleurs had a smooth rear derailleur hanger "bolt" which slid into an unthreaded hanger on the frame, or an unthreaded hanger plate, and a lock bolt/nut secured the der in place from the back of the hanger. ("Simplex-style".)>>
Yes the Jubilees have a hanger bolt that can screw into either a derailleur hanger on the frame or attach by a Huret derailleur mounting bracket that is later bolted onto the frame. Please note, Jubilee derailleurs were not made to directly fit a Campy dropout, a derailleur mounting bracket must be used. The way to tell is if a Huret dropout is used where they have an etched Huret on the outer dropout side. Jubilees were commonly used on mid-high end racing bikes such as Raleigh Competition, Rene Herse, etc. Jubilee derailleurs do not work well with Campy dropouts because the mounting position for the angle of the derailleur is wrong. I have heard of past owners using a dremel grinder to "fix" this, but it sounds too risky to me...
