ANEC II

ANEC II (1924), painted as G-EBJO, the Shuttleworth Collection’s ANEC II, the only one built, designed by W. S. Shackleton at Addlestone for the 1924 Lympne two-seater trials: a wooden, fabric-covered high-wing monoplane with a long, square-tipped wing of 38 ft span set on top of a slender fuselage, parallel lift struts to the lower longerons, a single open cockpit under a cut-out in the trailing edge and a 32 hp ABC Scorpion II flat twin across the nose, shown standing tail-down on its strut undercarriage and tail skid as restored in 2004 and flown at Old Warden: red fuselage with yellow lines and a yellow disc, ‘G-EBJO’ in white outline letters on both sides, a polished aluminium cowling, aluminium-doped wings and tail with the registration in red above and below, a Civil Air Ensign on the rudder and a varnished propeller with white and green tips (shape from the 1924 NACA three-view, with the undercarriage, cockpit, fin and rudder and engine following photographs of G-EBJO).

History

The ANEC II

The Air Navigation and Engineering Company of Addlestone, in Surrey, grew out of the wartime Blériot and SPAD Manufacturing Company, and in 1923 its chief designer, W. S. ‘Bill’ Shackleton, drew the ANEC I, a single-seat ultralight monoplane for that year’s light aeroplane trials at Lympne. One ANEC I shared the Duke of Sutherland’s and the Daily Mail’s economy prizes with the English Electric Wren, each flying 87.5 miles on a gallon of petrol.

For 1924 the Air Ministry ran a new competition at Lympne for two-seaters, with engines of no more than 1,100 cc, and Shackleton enlarged the design into the ANEC II. It was a wooden, fabric-covered high-wing monoplane with tandem open cockpits, a wing of 38 ft span and 28 per cent more area than the ANEC I’s, braced by struts to the bottom of the fuselage, and a 1,100 cc Anzani inverted-V twin, the largest engine the rules allowed. Only one was built, registered G-EBJO. At the trials that autumn the Anzani gave constant trouble, and the ANEC II could not take a proper part in the competition or the Grosvenor Trophy race that followed.

After Lympne it was sold to G. L. P. Henderson, who fitted a 32 hp Bristol Cherub and a strut undercarriage with larger wheels for better ground clearance, and a larger rudder. Norman Jones raced it, and in 1929 Allen Wheeler bought it and flew it widely. By 1931 it lay at Old Warden without its engine, undercarriage or instruments; Jimmy Edmunds, a friend of Richard Shuttleworth, rebuilt it within six months with an ABC Scorpion engine, and from then on it was flown as a single-seater from the rear cockpit. It passed through three more owners before its registration was cancelled in 1937, and the remains came back to Old Warden.

ANEC II G-EBJO

G-EBJOThe airframe modelled

G-EBJO is the only ANEC II built. The Shuttleworth Collection stored its remains at Old Warden for decades until Don Cashmore, who also built the Collection’s General Aircraft Cygnet, rebuilt it to its post-Lympne form: a single cockpit, Henderson’s strut undercarriage and an ABC Scorpion II flat twin. It flew again on 2 March 2004 and is flown at Old Warden in calm weather. The model shows it as photographed there, standing tail-down on its wire wheels and tail skid: a red fuselage with yellow lines along the longerons and a yellow disc under the cockpit, ‘G-EBJO’ in white outline letters on both sides, a polished aluminium cowling with yellow edging, aluminium-doped wings and tail with the registration in red above and below the wing, red struts and undercarriage, a Civil Air Ensign on the rudder and a varnished propeller with white and green tips. The shape follows the 1924 NACA three-view, with the undercarriage, cockpit, fin and rudder and engine taken from photographs of G-EBJO.
