If this 43 unregistered buses are related to the MkIV notice
tendered by SBST, it is likely that one bus is sold.
But no news of one MkIV is sold. Do note about the increasing trend
on DM3500s transferred to HGDEP.
Non of the MK4s are de-registered yet. The sold MK4s are likely
to be those without lifespan extensions as they are going to be
sold with 72 of the Leyland Olympians that will go by next
year.
