Having recently had to remove a steering wheel to change an indicator switch assembly I can confirm the securing nut socket size to be 1 5/16" AF.

Hello all,
a very comprehensive list and a real mixture of threads, (although the 1930's Morris Minor engine had metric threads with Whitworth hexagons) my only correction being the hockey sticks are 2 B.A. not 4.

That's what you get for buying French engines!!

Hello cam,
quite correct, that is what Herbert Morris did, i can't remember if it was Hotchkiss he bought?

Hi Alec,

It's certainly what Herbert Morris did! It was Hotchkiss et Cie, a French armament firm with a branch at Coventry. They produced the Hotchkiss engine for Morris which was based (close but not exactly the same) on the continental 'Red Seal' engine already in production in 1919.
