1906 February 7th. The company was registered to acquire all but 7 shares of the capital of H. H. P. Deasy and Co. Directors included Kenneth Hugh Buchanan. Plan to build 250 cars per year. Edmund W. Lewis is engineer and works manager. [1] [2][3]

The Deasy Motor Car Manufacturing Co took over the factory used by the old Iden Car Co at Parkside, Coventry. The vehicle designer was Edmund W. Lewis of Rover and Daimler fame.

From the outset Deasy and Lewis were at loggerheads over the way things should progress, the main problem being the lack of urgency in getting vehicles to customers. There was no doubt that the company was undercapitalised and paying the wages on a Friday was always difficult. Nearly all the components in the vehicles were bought in, but the machining was of indifferent quality and much re-working was required, smoothness being at first sacrificed for expediency.

1906 A. C. Hills employed. William George Williams appointed works manager.

1906 November. Details of their 24 hp car.[4][5][6]

1908 March 9th. Deasy became increasingly frustrated with this state of things and resigned. Lewis was relegated to Consulting Engineer. William George Williams was appointed managing director and H. A. Smith became works manager.

1908 November. Details of the 15-hp car.[7]

1909 John Davenport Siddeley joined the company as managing director along with George Roddick

1909 November. Details of the Deasy 15-hp and 25-hp cars.[8]

1912 Company changed its name from the Deasy Motor Car Manufacturing Co to the Siddeley-Deasy Motor Car Co [9]


Employees known to have worked for Deasy are Albert C. Hills, Hubert C. Clark, Albert G. Asbury, Percy J. Barker, Albert Hayfield, Edward Flogdell, J. A. Simmons, George T. Mason, Edgar Goddard, Walter Kimber.[10]
