A Blenheim Mk.V, initially known as the Bisley, fitted with an under-nose gun position. Note that, unlike the Mk.IV, the Mk.V cross section in front of the cockpit is symmetrical from just behind the nose to the windshield. The type was used by Bomber and Coastal Commands (who operated this example). It was built by Avro and Rootes in addition to Bristols, from whom photo was obtained.
