These cable runs not surprisingly are for Simplex cable operated front and rear derailleurs. Simplex offered a front double lever which worked just off a right hand boss. And there were two front derailleurs which could be used this way the JUY 56 and another earlier one from about 1953. The rear derailleur could be anything from a Tour de France, JUY 51 or others right up until the end of the push rod convolute spring gears in 1960/1. There were no restrictions preventing any form of advertising on frames in the 1950s it was probably somebody's personal choice. Regards Hilary
