all of the above, CEI 20TPI and BA. Typically BSW for threads in alloy, CEI 26 TPI as standard thread, BSF in cylinder, BA for electrical (switches on combination levers (5BA), magneto etc), CEI 20 TPI on footrest rods and bigger studs. :D
BSA 1930s nut.

Trying to collect all 1936 models. Still missing B3, R17 and Y13.
