A die cast bus, one of many I have bought over the years. It's a 1/72 scale version of my local bus that operated from 1970. Unfortunately, it doesn't display my local route but another operated from the same depot in Guildford.
Preserving the real vehicles is a big thing in the UK. This design was only built for London and the surrounding counties. But a few of these were later sold on to Malta for further use, and in recent times, some of these have returned to Britain for preservation.
