Around this time he was working as a freelance artist although some of his work was being used by The Motor to illustrate a weekly series of famous corners on racing circuits.

The start of war in 1939 brought a cessation of motor racing for the duration and Nockolds carried on working from his London studio as a general illustrator and for the services, particularly the RAF producing propaganda art. 

In 1942 he was asked to look at improving the camouflage of night fighters. He noticed that a white owl was more difficult to see against a night sky than a dark bird. His idea was to paint the leading edge of the wing and underside of the aircraft white and the top of the aircraft black making it difficult to see from above and below. He prepared a painted model of a De Haviland Mosquito aircraft which was transferred to a full sized plane, resulting in the whole of 151 Mosquito Squadron being converted to the new scheme within days. Other camouflage work led to him being called up into the RAF at the end of 1942, initially as a Clerk, but by 1943 he was posted to the aircraft research station at Farnborough where he had civilian status. He continued the propaganda paintings and his work on camouflage of aircraft, particularly bombers and accepted commissions to supplement his income. The end of the war saw the restart of racing and he resumed his motoring artworks including commissions from car makers such as Ford, Standard, Rover, Rolls-Royce and the Rootes Group and component manufacturers such as Lockheed and Lucas.

It was during this period that he was commissioned by Jaguar and some of the sponsors and suppliers to produce all the paintings that we have in our Artwork Collection. Nockolds’ connection with Jaguar began when the Esso Petroleum Company commissioned him to depict Le Mans 1951 when Peter Walker and Peter Whitehead drove their C-type through pouring rain to give Jaguar their first victory at Le Mans. He then worked closely with Jaguar’s PR Manager Ernest (Bill) Rankin for the next decade undertaking a series of commissions, many of race winning situations but also pictures for calendars, Christmas cards and advertising posters. He was a master of combining light and texture into his work to give the impression of speed and this comes across in several of our paintings.

His work was displayed in many exhibitions in the UK and twenty-four of his paintings were exhibited in New York in 1960 in an exhibition entitled ‘British Motoring Achievements’. This was a collection of paintings depicting outstanding performances of British cars during the previous ten years including some of our race winning Jaguar pictures.

Nockolds took a very keen interest in the Brooklands society founded in 1967, being an early Committee Member and the Chairman from 1976 to 1978, only resigning with the onset of ill health. He was elected Chairman of the Guild of Aviation Artists in 1975, and continued to paint late into his life before passing away in 1979.
