Top Deck Travel, Woking

Now then. A challenge. What on earth is this? I know it's a Caetano but that's as far as it goes. It could be a Ford chassis maybe? It was snapped in August 1984 at the former Woking premises of Top Deck Travel, famous for overland tours in converted Bristol Lodekkas. A Google for info reveals Top Deck did indeed operate a few coaches so maybe it was one of these? VEA590M is a possibility.
