name New Zealand Avenue, the Wellington Pub (formerly The Kiwi), and a small memorial in the Homebase car park. Walton upon Thames Urban District merged with Weybridge Urban District to form Walton and Weybridge Urban District in 1933. In World War II, owing largely to the proximity of important aircraft factories at nearby Brooklands, the town was bombed on various occasions by the Luftwaffe. On 27 September 1940, fighter pilot F/Sgt. Charles Sydney, who was based with 92 Squadron at RAF Biggin Hill, died when his Spitfire (R6767) crashed in Station Avenue. He was buried in Orpington and was commemorated by a memorial plaque adjacent to the former Birds Eye HQ close to the crash site although this has recently disappeared with current major redevelopment of the Birds Eye site with new apartments. Hopefully the memorial will be re-erected and re-dedicated later. Hersham and Walton Motors (HWM) constructed its own racing car in the early 1950s. Stirling Moss competed in his first Formula One Grand Prix in an HWM. HWM was the world's first Aston Martin dealership that diversified into Alfa Romeo in 2009. Walton Town hall, which was commissioned to serve as the offices of Weybridge Urban District Council, was designed by Sir John Brown Henson and Partners in the modernist style, featured a curved structure built from concrete with stone cladding and was completed in 1966. It became surplus to requirements and was subsequently demolished after Walton on Thames was absorbed into the Borough of Elmbridge in 1974.
