Until 1916 when the company was forced to close down (The manufacturing works were situated in Bittacy Hill, Mill Hill, London NW7. ) In June 1917 Ross Ltd. under the control of the Ministry of Munitions acquired the assets of the Company and operated the factory until 1919.
In 1909 the Director of Army Contracts reported the purchase of 1500 No 2 prismatic binoculars from Carl Zeiss, Jena, It became policy to avoid foreign purchases where possible. Zeiss set up a ‘
British
’ company so as not to be disadvantaged. Prior to the War the Company supplied approximately 1800 No 3 binoculars.

( 19 January 1918 Ross received a (continuous ? ) order for No 3 Mk ? Binoculars. Three weeks notice to end the contract was given on 12 November 1918. 910 were due by 12 February 1919, 800 were completed and 209 were rejected for remedial action. The contract was cancelled and Ross received £4500 compensation.)
During WW1 and WW11 all British binoculars that were used by the Armed Forces were stamped with the Ministry Broad Arrow.
At the time of WW1 there was a shortage of binoculars, so the military ‘bought in’ a lot of binoculars. These binoculars could have been French,
German
, or from private individuals ect, wherever they could find them.
