P.Lewis British Aircraft 1809-1914 (Putnam)
J.A.P.-Harding Monoplane
The J.A.P.-Harding Monoplane was constructed by J. A. Prestwich and Co. Ltd., of Tottenham, London, N., for the designer H. J. Harding, a racing-cyclist. It was an adaptation of the Bleriot Monoplane and was fitted with the eight-cylinder 40 h.p. J.A.P. engine. In its early state, it had rectangular wings with large ailerons, but very soon these were abandoned in favour of warping wings of the standard Bleriot pattern. The machine was first flown at Tottenham marshes on 10th April, 1910, and later at the Blackpool Aviation Meeting and in France by Harding; it is now part of the National Aeronautical Collection of the Science Museum, London, S.W.7. Span, 30 ft. Length, 27 ft. Wing area, 230 sq. ft. Weight empty, 510 lb. Maximum speed, 50 m.p.h.

JAP-HARDING monoplane (J.A. Prestwich & Co., Tottenham, London, N)
This well known manufacturer of motorcycle engines also produced light aero engines and, in 1910, built a monoplane fitted with one for demonstration purposes, to be flown by H.J. Harding, their Paris representative. The machine made its first flight on 10 April 1910 at Tottenham Marshes, but thereafter was taken to Amberieu in France, where Harding learnt to fly it, before returning to England without his pilot's certificate, due to a misunderstanding. He was thus unable to compete at Blackpool or Lanark in August.
The machine was generally similar to a Bleriot except for wings fitted with ailerons, hinged on the trailing edge, which were replaced in France with Bleriot type warping wings. Harding subsequently obtained his certificate and continued to fly the machine from Tottenham during the rest of the season. It was later handed over to the Science Museum, where it is still exhibited.

JAP
Although the JAP monoplane was not French - it was a British-built copy of the Bleriot XI, powered by a 40 hp JAP motor and built by JA Prestwich in London for HJ Harding. It began with ailerons, which were soon replaced by the Bleriot wing-warping arrangements; we are including it here, since it was often referred to in French aviation journals in 1910. It still exists, and can be seen in the Science Museum, in London.

Журнал Flight
Flight, April 16, 1910
An English Entrant for Lyons.
AMONG the entrants for the International meeting to be held at Lyons from May 7th to 15th, is Mr. Harding, who has recently been flying at Huntingdon racecourse. He has entered a monoplane fitted with a J. A. P. engine. The other entrants so far are Metrot (Voisin), Van den Born (Henry Farman), Latham (Antoinette), Molon (Bleriot), Legagneux (Sommer), Dubonnet (Tellier), Paulhan (Henry Farman), and it is also almost certain that Rougier will enter his new racing Voisin.
Flight, June 25, 1910
Harding at Amberieu.
MR. HARDING has been making good progress with his J. A. P. monoplane at Amberieu recently, and on Saturday he twice described a figure eight over the flying ground.
Flight, July 9, 1910
Harding at Amberieu.
MR. HARDING has been making good progress with his J. A. P. monoplane at Amberieu lately, and on the 1st executed two flights, one of 5 and the other of 15 kiloms. length, the altitude being about 10 metres.
Flight, July 30, 1910
Mr. Harding a "Pilote-Aviateur."
ON the 19th inst. Mr. Harding, who has been making some good flights at Amberieu, on his J. A. P. monoplane, successfully made two of the flights necessary to obtain his pilot's certificate, and later in the week he completed the tests. Moulthier, who has been practising at the same place with a Bleriot monoplane, has also passed the Ae.C. F. examination.
