It established a small factory on the Chilton Lodge estate at Leverton, near Hungerford in Berkshire, from which location the firm's name was derived.
The aircraft had a clean aerodynamic design, which required split flaps to lower the landing speed.
The four aircraft were stored during the war and the jigs, spares and half-completed D.W.2 were taken over by the College of Aeronautical Engineering at Redhill Aerodrome.
Aircraft consultants, called 'A and EP', checked the stresses for British airworthiness conditions and consequently the spar and joint fittings were strengthened.
Andrew Dalrymple was killed in a crash of a Fi Storch on 25 December 1945 near Hungerford, and this event soon ended aircraft production.
