By this time, Barr had returned to Scotland and to the University of Glasgow, where he had been a student, as the Regius Professor of Civil Engineering and Mechanics. He continued to keep in close touch with Stroud.
1892 The Admiralty adopted their competitive design for a rangefinder and gave them a contract for an initial six instruments. The mechanical parts of this rangefinder, known as NRF No 1, were constructed in the workshops of the instrument makers, James White in Cambridge Street, Glasgow. Optical parts, calculated and designed by Barr and Stroud, were manufactured up by Adam Hilges of London, initially at the expense of the inventors. Stroud raised funds for the project by giving popular magic lantern shows around Leeds.
1893 Company established.
1895 Barr and Stroud's Patents was renting workshop space at 250 Byres Road, Glasgow, but demand for the product soon necessitated a move to larger premises in Ashton Lane, Glasgow.
By 1904, 100 men were working for the company in a new purpose-built factory in Anniesland, Glasgow.
1909 William Stroud resigned his chair at University of Leeds and moved to Glasgow to work for the company full-time.
1913 Archibald Barr, in spite of a distinguished teaching career, followed his example and they formed a limited company.
1914 Manufacturers of scientific instruments. Specialities: Barr and Stroud rangefinders and fire control instruments adopted by the British and foreign navies. Employees 500.
1914 They began extensions to the Anniesland works in order to meet the sharp increase in demand for their rangefinders that followed on the outbreak of the First World War. The war years saw the development of other products, including a torpedo depth recorder, a periscope rangefinder and a dome sight for aircraft.
1921 Designed for motorcycle application, Douglas Barr (son?) tested out the capabilities of the single-sleeve-valve engine by installing his prototype in the frame and cycle parts of a 349cc AJS. The original machine remained almost unchanged, except for the engine. It was road tested successfully for several months in 1921 and made available to the trade in the November of that year, later to be joined by 499cc single and 998cc V-twin versions. (This information appears slightly erroneous as The Motor Cycle published an article in 1919. Barr & Stroud 1919 article )
