Hawker Siddeley Acquire Petter

In 1957 the company was acquired by Hawker-Siddeley and some production was moved to Hamble as the reorganized company was split into four groups within Hawker-Siddeley Brush Group—Petter Staines (small engines), Petter Generator Divisions, Petter Marine Division, Petter Service Division and Thermo-King Division (building refrigeration units under license from the US firm Thermo-King).
