Just going to mention that Cyclo Benelux mark 7 front rod shifter (1953) works really well.
My 1953 Holdsworth Whirlwind was originally 5 speed so no braze on for FD shifter.
I originally also tried Cyclo Benelux tourist 5 speed rear but the action is too heavy for me so went SunTour Cyclone mk1 GT.
