Just sorting out my cables and levers. I have a right mix of bolt most of which are rusty. What I cannot work out is the thread on the lever handlebar clamp. The are not 2 BA and the 2BA should fit 3/17 BSC. So I am a bit of a loss.
I am sure the levers are not original for a 1961 GF as they have a ball on the end but at least I have a matching pair.
I can get replacement pivots for the levers from Dragonfly but does anyone know what the threads are. It would be great to tidy these up and I am not keen to spend £70 on new levers.

Clamp threads are 1 BA.
Pivots are 1/4 x 26tpi BSF.
Some information below.
Modern repro items may have different threads.

Wow thanks Julian for the complete and comprehensive answer in such short time too.
