I think that both under bracket rear derailleur cable routing and internal rear brake cable routing was both earlier and more common than Jan Heine supposes. Chuck mentioned that his 1950s Hetchins had under bracket cable routing - it was pretty much standard on all Hetchins with derailleur gears with bare wire cable routing from about 1950 onwards and I would guess was one of Jack Denny's ideas. Hetchins with Cyclo Standard gears (a rare but not completely unknown sight) of course had enclosed cables. As to internal rear brake cable routing this was not uncommon on French tourers or racers in the 1940s/50s and certainly Armstrong in England for one used it on a road bike model in 1949. And I am pretty certain I have seen Italian road bikes from the 40s/50s with internal rear brake cable routing.
