English: Cheddar Gorge Tour bus (reg. WYV 67T), a 1979 Leyland Titan (B15), pictured picking up passengers at Gough's Caves in Cheddar Gorge.

The 91st production Titan, it's from the early batch built by the British Leyland subsidiary Park Royal Vehicles in Park Royal, London (later ones were built at Leyland's expanded factory in the Lillyhall Industrial Estate, Workington). As with the vast majority of production, it was delivered new to London Transport as part of the dual-door T-class, allocated fleet number T67.

In March 1993 it passed to dealer Ensignbus, who sold it to British Bus subsidiary London & Country in October that same year. Operating as their No.925, it passed into the fleet of Londonlinks during the 1995 British Bus reorganisation.

In 1997 it was purchased by London Pride Sightseeing, who converted it to a half open top bus (retaining the forward three window bays of the upper deck and roof).

In 2001 it passed to Cardiff City Sightseeing (No. 282), by which time the rest of the roof and upper deck side windows were removed, leaving just the front windows.

By 2005 it was with Cheddar Gorge Tours. The tour is operated by Longleat Estates, who also operate many of the attractions in the gorge.
