Re: Blenheim IV F with 20mm Cannon

Most of the 113 Squadron Blenheim Mk IV-F aircraft had the local modification of along barrel 20mm Hispano cannon mounted on the floor of the Observers position and projecting through the starboard panel on the bomb-aiming window. This 'lash up' blocked the emergency exit, and the ammunition feed caused the pitot tube to be moved forward.
