They never had a Bendy with a smiley face. It was a Volgren body
with Hino Chassis. I still have the newspaper cutting.
The TIB973 to TIB 1001 series of Articulated buses may give you the
impression that it has a smiley on it, but in actual fact, that was
part of the bodywork and was not intentional placed on the bus.
Instead. TIB 950R has the honour of having the only similey painted
on it, and it last at least for 2 years.
