Introduction

We are still in Willesden for series four.  Series Four lacks a good deal of locations that can be explored.  We seem to be all over the place, judging by the places I've found.  There's an abortive school trip to France, with an unknown school that we start from, and there's a few scenes at the back of the demolished school.  There's a few incidents on a bus which haven't been located.  It looks to me like the bus stop we see is faked - it seems to rest on a plinth. Is that a 55 labelled on the bus stop, next to 52?  The 55 went out of commission in 1968, and didn't cover the same area as a 52.  On the other hand, the bus itself, a 52 did used to run to Willesden, the apparent location of the school by series 3 and 4 - moreover, in 1981-2, the bus still went as far as Mill Hill.  Once it went as far as Borehamwood, the long-term home for the series after series 8, but was replaced by the 292 in 1969.  Anyway, considering the route of the 52, along predominantly busy roads, the location of the bus stop - in a seemingly suburban street, doesn't quite fit.  Perhaps the faked location can still be found - it seems to be on raised ground, perhaps near a railway underpass.
