The Volvo Ailsa was developed as an answer to the engineering problems that were caused by rear-engined buses. The engine sits between the drivers cab and the door, which has three leaves to allow clearance for the engine compartment. The VA is easily identifiable by the large front radiator grill.
London Transport obtained second hand examples after buying three models, including V3 the double-door double-staircase bus, for evaluation. By the time I photographed it the rear door had been removed.
Why Jenny's page? In honour of her confidently pointing out an Ailsa, when we were on a trip to Glasgow, much to her dismay!!
Information about the Volvo Ailsa in London can be found in: 'An illustrated history of London buses' by Kevin Lane.
