Its core operations were from a 60-acre (24 ha) site in Stoney Stanton Road in the English city of Coventry, Warwickshire.
The new company bought (as from 1 January 1905, six months earlier) from Cammell Laird the ordnance business established in the late 1890s by H H Mulliner and F Wigley which had been moved by them in 1902 from Birmingham to the 60-acre (24 ha) site in Coventry's Stoney Stanton Road.
[note 2] By 1909 Coventry Ordnance Works had establishments, as well as at Coventry, at Scotstoun for manufacture of ordnance and gun equipment; for cordite shell loading and explosive magazines at Cliffe; and a gun-proving ground with a land range of 22,000 yards at Boston and was handling an order for 12 inch mountings of one of the new battleships.
At Scotstoun a new factory had been built with a wet dock, pits and machinery for the erection and transhipping of the heaviest guns and mountings[2] and hydraulic barbettes of the firm's own design but it was unused until 1911.
[5] By early February with admiral Bacon on board and Mulliner off it the directors could report an order from the British Admiralty for the mountings of all the heavy guns of one of the latest battleships that brought into operation for the first time the most costly and most important part of the company's new plant[2] ending a long difficult period for Coventry Ordnance Works.
Little investment was made and the firm had to seek civil engineering contracts away from shipbuilding in order to minimise losses.
In 1969 the works was sold to Albion Motors, whose main factory had been situated on the opposite side of South Street.
