During the war, it was not all work since Jack was a keen guitar player and often played with Cyril Lingwood in the Altona Band and Cyril recalls that Jack was a keen fan of Django Reinhardt and often listened to music of the 'Quintette du Hot club de France' while staying at the Priory – in fact Jack's guitar playing style was probably heavily influenced by Reinhardt.
While there were relentless long hours and a six-day working week, Jack found time to court and marry 'Margaret Wilson' who at that time was in charge of the telephone switchboard at Cowbridge House.
At the end of the war, Jack was called back to Southend to help post war radio production get started but this was not to last for long since by December 1946 he found himself back at Malmesbury in the hastily reformed WDU in the High Street, which shortly afterwards moved to Cowbridge House with Jack and family moving yet again to the 'Pre-Fabs' in Cowbridge Crescent.
This was undoubtedly to begin work on Cloud and Collision Warning Radar where TRE and EKCO worked in collaboration to research and build the world's first 'Weather radar', which became the E38 system following extensive trials in a RAF Shorts Sunderland flying on what was then known as 'the empire routes'. Jack would have flown on many of these flights not only ensuring that the system worked well but also training the operators in the use of the equipment.
By 1949 this system was available for sale and it is believed that the DH Comets were so fitted.
Evolving out of this system was ASV Mark 19 and records show that both Jack and Frank Oxborough were heavily involved in 'service trials' of this system.
By this time Jack had been promoted to become a 'Senior Engineer' and was in charge of the radar lab located in the 'Orangery' and under him (to name a few) he had Jack Halsall, John Smith, Frank Oxborough, Frank Burnill, Renton Hudson, Norman Tingey, Mike Start, Jeff Saunders, Dave Snelgrove, John Jewsbury etc.
From 1951 onwards this team worked hard on developing the E120 system, which entered service in 1955. Jack was involved in many of the test flights on the Bristol Britannia and records show that he traveled extensively in the test and route proving flights of this aircraft.
At the Christmas 1955 staff party, Eric Cole presented Jack with a gold watch for his 25 years service to the company. Sue Jameson (his daughter) still has the watch, which keeps very good time and is now a valued family possession.
