Subject: [CR]Late '50's derailleurs for stamped dropouts-which?-how?

I have a project in the works which requires a rear derailleur appropriate to a late '50's Jack Taylor Clubman frame with stamped dropouts,no hanger.It has a single brazeon for a downtube shifter,originally Cyclo-Benelux.My question is: Which derailleurs from that period could be used with the stamped dropouts,and without some sort of funky retrofitting?The Gran Sports and Allvits I've seen sometimes include a bolt-on hanger.Are these universal fittings? And would a Simplex shifter from that era have threads compatible with the Cyclo-Benelux shifter boss?Also,when was the Simplex Tour de France discontinued?Many questions...
