In 1919 Prestwich formed Pencils Limited to exploit his invention of new machinery and the company made Master Pencils, also in Tariff Road. In the nineteen thirties engine production increasingly focused on small industrial and agricultural engines. During WWII Prestwich produced around 240,000 industrial petrol engines in support of the war effort, together with millions of aircraft parts, fuses, etc. In 1951 the assets of J.A.Prestwich and Company Limited and Pencils Ltd were taken over by J.A.Prestwich Industries Limited which was registered on 23 April 1951 and floated on the London Stock Exchange shortly after. By 1957 practically all the shares in the company had been acquired by Villiers Engineering Company Limited of Wolverhampton, which also made motorcycle and industrial engines. The engineering works in Northumberland Park closed in 1963 and J.A.Prestwich Industries Limited was liquidated in 1964.

Variants included the use of 4 valve heads, twin spark plugs and early electronic ignition systems. Some were modified to run as alcohol fuelled engines primarily for speedway use. All the engines were 4 stroke. Use of the engine declined in the 70's as competing engines from Jawa-CZ and Weslake were developed giving better performance.

Aircraft engines

Early aircraft were light and basic, and needed a reliable lightweight engine for power. JAP motorcycle engines were often used in this application. A JAP engine was originally fitted in A V Roe's 1909 triplane, regarded as the first all-British aircraft, and for a while Prestwich and Roe had a partnership. JA Prestwich at first would deliver the same engine to the aircraft manufacturer, allowing them to make local modifications – mainly larger venturi tubes for the carburettor, to allow for greater air intake at altitude. In the late 1920s and early 1930s JA Prestwich produced various heavier engines under licence, including those for the UK market for Aeronca.

Motorcar engines

The engine had a larger flywheel than the motorcycle engine and an enclosed magneto drive. The engine was illustrated fitted to a Morgan three-wheeler. In light of JAP's development of high-powered light engines for speedway, some low volume pre-war car manufacturers, including G.N., T.B.,

Utility engines

J.A. Prestwich also made small utility engines under the JAP name for a variety of uses, both stationary and in motorised equipment. They ranged in size from the smallest model 0 two-stroke engine to the much larger type 6 engine, and were used on rotovators, generating sets, milking sets, water pumps, lawnmowers, hay elevators and other agricultural machines. Most were 4-stroke, but there were some 2-stroke engines such as the model 0; they were quite reliable, and examples can still be seen at vintage rallies around Britain. While most of the engines bore the JAP name, some, such as the model 3 OHV engine made for Arthur Lyon & Co for their ALCO generator sets, had timing covers with the name ALCO Featherweight cast in. J.A.P. also had a factory in Chelmsford Road,
