Current Projects chat and miscellany

generally speaking, do they make some appropriate respectable old school brake levers which use hidden cable routing that would fit on a build like this?

The contemporaneous DuraAce AX levers could be used and keep it period correct, or I think there would have been Dia Compe Aero Gran Compe levers as an option. Concealed cables across the board didn't arrive for another couple of years.
