I've found the perfect looking brake lever for the project - and of
course they're impossible to get. It's the Sturmey-Archer BLS92:
A few European shops list only the left side as it's apparently factory stock on a particular Gazelle model (of course it would be). Otherwise, it is elusive, and I have a hunch that neither QBP or J&B will stock these.
I've also been toying with the idea of changing the crankset out to something square taper and 175mm,
but I don't like the look of 5-arm spider cranksets on old Raleighs.
I do like the look of three-pin cranks on these though and I do have a TA Pro 3 Vis on hand. I don't have a 46t ring for it though (and I think I'd prefer the ring to be black, which doesn't exist).
