There's a b&w photo of the bus, with a contingent of "Wehrmacht troops
and the Big Ben tower behind. The bus is an AEC, number DLU92, with the
destination indicator saying
159
STREATHAM COMMON
LAMBETH BDG BRIXTON

And the cover has a close-up in colour of the driver cab, with a pair of
identification plates reading "AK 15".

A quick bit of Googling suggests that makes it an AEC Regent I,
delivered to LT in June 1937 and originally allocated fleet number STL
2093, allocated to Cricklewood Garage.

Its final London allocation was to Stockwell (hence the AK running
plate), before disposal in 1955. It spent a few years with Reliance
Motor Services of Newbury, running with fleet number 39, before being
purchased for preservation by a Mr D Cowing in May 1958.
