Seen early on is this VDL Synergy of The Kings Ferry:
A badly cut sequence features Arriva London T186 (LJ60ASZ, an ADL E400), arriving at a bus stop on route 150 to Becontree Heath The footage where Adkins and Greene board and climb upstairs is from an AEC Routemaster, while the E400 is seen leaving the bus stop:
They hold a conversation aboard the RM, then a different E400 is seen as part of the same sequence, on route 150 to Chigwell Row (heading in the opposite direction from T186):
Also seen is a second Kings Ferry vehicle, FJ12GBO, a Caetano Levante bodied Volvo B9R:
