"B&B" stands for "Borg and Beck", which was a company that made clutches
(among other things).  They no longer exist as a separate company, only as a
name (that like "Lucas" has been sold and re-sold).  But "back when" they
made lots of different clutches, for different makes, models and years of
cars.

So with regards to Triumph TRs, we have at least the "3-finger" B&B clutch
used on TR2-4, plus the "diaphragm" B&B clutch used on (at least) some
TR4A-TR6.  Then there are actually several different B&B clutches that fit
the TR4A-TR6, as documented in the articles by Brent Kiser & Nelson Riedel.

(I don't know offhand what the TR7 & TR8 used.)

When it is important to distinguish, I suggest "3-finger" for the B&B TR2-4
clutch, and "B&B diaphragm" for the B&B version of the TR4A-TR6 clutch.
