It went metric actually. Then it died.

Unified first, then metric. Not straight from BSW/BSF to metric.

Yup. Most UK made cars were Unified (in the main) from after WW2 to about
'70. Although electrical parts stayed with BA.

But pre-war designed parts often stayed with the older threads - one
example being the MG XP series of engines that continued in production
until the mid '50s. And they had some strange threads - the big end bolts
were an extremely fine one - not BSF. Rileys too - until both makers
adopted the BMC drive train. Although general purpose nuts and bolts might
well have been Unified.
