P.Lewis The British Fighter since 1912 (Putnam)
During 1917 Farnborough’s brilliant fighter designer H. P. Folland had vacated his position at the Factory and joined the Nieuport and General Aircraft Co. Ltd., at Cricklewood, where he was soon responsible for the firm’s first original design, the B.N.1, which was started early in 1918. As was to be expected from the Folland drawing-board, the resulting single-seat fighter was a workmanlike design with clean and appealing lines. Although stagger was employed widely to improve view, it was not embodied in the B.N.1’s two-bay cellules and another unusual feature, which Folland had used on his earlier S.E.4, was the fitting of single I-type interplane struts. The normal fuselage-mounted twin Vickers guns were augmented by a single Lewis gun on the upper centre-section. The B.N.1, wrecked in a crash on 10th March, 1918, was designed to use the 230 h.p. Bentley B.R.2 and displayed a vertical tail outline which revived the shape employed on the S.E.2a and S.E.4.
H.King Armament of British Aircraft (Putnam)
B.N.I. A counterpart of the Sopwith Snipe, and resembling that type and other contemporary single-seaters in having provision for an over-wing Lewis gun as well as two Vickers guns with C .C gear, the B.N.I was designed in March 1918. The Lewis gun was actually fitted on this machine, being positioned somewhat to starboard, and the Vickers guns were semi-internally mounted, beneath a humped cowling. The makers advanced the claim that although the 'anti-airship'Lewis gun installation on the top wings of other lighters was disliked by many pilots, being too high above their heads 'to permit it to be directly sighted on a target in the best fighting attitudes', the gun on the B.N.I was 'practically in line with the pilot's eyes'.

NIEUPORT (& GENERAL) B.N.1 UK
The Nieuport & General Aircraft Company was established in November 1916 for the purpose of manufacturing Nieuport designs in the UK. When H P Folland joined the company following dispersal of the Royal Aircraft Factory design office, work began on an original single-seat fighter. Designated B.N.1 (the initials signifying ‘‘British Nieuport”), the new fighter was not related to any French Nieuport design and was an equi-span, two-bay, unstaggered biplane powered by a Bentley B.R.2 nine-cylinder rotary engine. Of fabric-covered wooden construction, the B.N.l carried an armament of two synchronised 0.303-in (7,7-mm) guns and a gun of similar calibre above the wing centre section. Three prototypes were ordered and the first of these was flown early in March 1918. After destruction of the prototype in a crash on the 10th of that month, development was discontinued and the remaining two prototypes were scrapped before completion.
