Assuming that we keep them all, Worcester Padmore Street depot now has a numerical run of 13 double-deckers -- -- 33858-70.
I believe the biggest numerical run before now was 10 -- -- 6046-55, in 1967.

Ignoring pre-Midland Red trams, can anyone confirm or correct this ?

Other than Oldbury depot when the trams ended, Midland Red didn't really allocate buses in fleet number sequence, so I would imagine you are correct.
