The Beast . 1950's era Thames Trader.

All the busses went through several colour scemes and The Beast more than most ,although it always had a full set of razor sharp teeth and the single eye of Horus in the middle of its forehead [this on account of the beast being the slowest of all our vehicles and so always leading the convoy and therefore being the bus that most needed to see where it was going. None of the other busses having eyes they would follow blindly like lemmings over
the cliff and into various wet meadows and sinking bogs.]
