.er... the BA was an effort at going metric! Then there was BSF, BSWhit
BSBike, BSPipe, RAS and several others that I forget.

I thought it was bad enough with a Morris Minor I once owned that,
depending on what I was working on, required either metric, inch, or
Whitworth sockets.

Didn't know how lucky I was...

well...there's SAE of course, and metric both sure to be found on
recent US production.
But there has been Unified, ANC, ANF, NatStdPipe and a few others I
forget....
