[Tigers] Rootes using BMC stuff

[rande]

There is the often repeated thought from Sunbeam book writers that Rootes could
hardly wait to find another supplier for Alpine carbs other than SU, as Rootes
didn't want to feed BMC coffers, and that supposedly is the main reason the
Alpine Ser. V was switched to Zeniths.

But, I have a question. Who supplied the original Tiger fuel pumps?. If it's
Smiths or SU, weren't there other manufacturers to turn to, as well?
