Standard Motor Products Ltd was unusual in the Australian motor industry because of the high Australian shareholding of the company; 88% in 1952 when the Australian company bought out its English partner. The remaining shares were held by the Standard Motor Company (SMC). As a sign of the close co-operation between the two companies, SMC's Sir John Black was made president and Arthur Crosby remained as chairman. His brother, Clive Crosby, became the managing director. By 1956, the factory employed over 1,600 workers.
