The business was operating from the Hubert Street Bradford address in late 1895 making arc lamps and electrical instruments.
The company itself was voluntarily wound up 11 June 1923 following the 1921 transfer of all its assets to post-1918 owner English Electric where its operations continued.
[4] In February 1903 Phoenix Dynamo purchased the whole of the works, business and patent rights of Bradford's Rosling & Fynn Limited (in liquidation) and announced that after some extensions to the buildings were complete those operations would be consolidated at Thornbury.
[note 1][6] The lack of information on this business's activities could be attributed to its pre-war Admiralty and War Office contracts.
It produced millions of shells, a large quantity of machine tools and the fastest and biggest sea planes and flying boats.
