The demo aircraft is the BOAC unarmed high speed courier aircraft, which features in the http://www.justflight.com/product.asp?pid=318 - Mosquito Special Ops - Upgrade Pack A . This variant was adapted to carry one passenger in an extremely compact  compartment in the bomb bay on high-speed envoy missions. The BOAC markings were an attempt at trying to convey to the enemy that the aircraft was unarmed, although the Mosquito's enviable high speed performance was a very handy defence!
