There were plenty of 12-car trains *through* London Bridge before the 1990s
platform lengthening, but they didn't stop.

Sometimes, they did, especially during disruptions - country end off the
platform both ways. It wasn't uncommon.
This was before problems with stopping at short platforms - don't forget
that although the track layout permitted 12 car trains into platforms 4,
5 & 6 at Charing Cross, the platforms were just over 11 cars long. At
Orpington (down) the back two hung off, which could be a problem,
especially with HAPs.

I'm trying to think of a scheduled 12 car stop at London Bridge, and
offhand I can't. I can also only think of one occasion when a 12 car
train I was working did so (*), but I didn't work that many 12 car
trains on the Eastern side.

(*) One Saturday morning with the 0730 Charing Cross to Folkestone
Harbour / Ramsgate via Dover
