Another memory: The early Morris Minor cars (split windscreen, sidevalve
engine) had mostly BSF threads, but the gearbox had Metric fine threaded

Nuffield group used oddities for some things - cycle threads with BSF
hexes. Could be those threads are close to metric fine. First really
noticed them as big end bolts on an MG XPAG engine.

I wasn't completely sure about this. You probably are correct (the clue
being in the English spanner sizes). The threads were certainly very fine.
Now BSF isn't a particularly fine thread, so using a Cycle thread may not
have been such an odd thing to do, after all
