DOUBLE DECKER BUS - a souvenir/merchandise enamelled badge (c.1980s)

Postage is extra.

.
For sale is a double-decker public transport service bus in a yellow and blue livery. I've been unable to identify which make of bus or which livery it is, but if anyone can tell me which, I'd be grateful to hear from you.

This type of badge would originally have been sold as a merchandise or a souvenir badge from a visit to a vehicle preservation society or exhibition rally.
