Anyone who has studied Bedford OXA Armoured 30 cwt Lorries in WW2 will know that they were built as an expedient in 1940 due to the loss of so much at Dunkirk etc. And yet here we are in spring 1942 or later with a Bedford Armoured Lorry on guard in the background?

I doubt this is an Avro Lancaster factory airfield and more like an RAF one, as suggested by the RAF personnel. Incidentally many of these Bedfords, including the 3 tonners with COW guns, were passed to the RAF, so I consider it to be an RAF vehicle.
