As for
extra stock - where did it all go when the line was cut back to
wealdstone?

It still had 1959 and 1938 stock back then, so the answer is either
for scrap or the Isle of Wight.


IIRC there were only 4 more units involved when services ran to
Watford if you simply took the contemporary services beforer and after
when Watford was axed.
