LS 185? No - LS 401
A post on The AEC Society's forum leads me to think that this is probably LS 185, at Aldenham after a relatively minor accident. Eventually it was cannibalised for spares.
I have one doubt about its identity, as it seems to have garage markings for Bromley (TB) and a Bromley route number showing (146). LS 185 was apparently at Leyton garage when the accident occurred in June 1983.
Metrobus M66 is sneaking into frame on the right.
