[2] Toward the end of the 1930s Marshall superchargers were listed by Sir George Godfrey and Partners (Holdings) Ltd of Hanworth, Middlesex, made by them to the designs of J.W.
[4] In 1990 Adams Ricardo Ltd purchased the rights to the Wade and Godfrey compressor ranges from Howden.
While the supercharger was initially used for increasing the performance of sports cars such as the MG and Frazer Nash, in 1939 Sir George Godfrey and Partners suggested to the Air Ministry that they could be used for cabin pressurisation in aircraft, for which purpose many were made during WW2.
The cabin pressurisation increased the altitude at which aircraft could fly and so was a closely guarded secret during the war.
However key members of the Nordec company left late in 1947 to form Wade Superchargers Ltd. Sir George Godfrey and Partners launched the K200 Marshall supercharger after the war, designed for the commercial vehicle market.
