AB Thulinverken was a company in Landskrona, Sweden, founded in 1914 as Enoch Thulins Aeroplanfabrik by the airman and aircraft technician Enoch Thulin. The company became Sweden's first aircraft manufacturer. In 1920, Thulin also started manufacturing automobiles, which continued until 1928. During World War I, the company came into financial difficulties and was reconstructed in 1922 as AB Thulinverken. The manufacturing of brake systems became a main focus of the company. In 1958, Thulinverken merged with Svenska AB Bromsregulator (founded in 1913). The remains of Thulinverken are now a part of SAB Wabco AB, which is owned by the French Faiveley Transport company since 2004.
^The 50 hp Gnome Omega engine fitted to the Thulin A aircraft (a licence-built Bleriot XI) is sometimes described as a Thulin engine. Although Thulin did make Le Rhône motors under licence, the Gnome engines were particularly difficult to manufacture, and it seems unlikely that Thulin actually built any, since the Omega was very outdated in 1916 when he first started making engines in his new Landskrona factory. Thulin didn't fit the Omega engine in any other aircraft.
^The Thulin H was a 3-engined bomber, possibly of Thulin's own design. It had one "puller" engine in the nose and 2 "pusher" engines in wing nacelles. Source:Professional Pilots Network forum competition, with photo.
^A web search in October 2013 reveals nothing about the Thulin M other than its existence in lists of aircraft.
^The Le Rhône 9C and 11F engines were manufactured under a licence acquired by Enoch Thulin from Gnome et Rhône in 1915. They were both derived by Le Rhône from Verdet's original 7-cylinder 50 hp model 7A, with the same piston dimensions. Thulin licence-built engines apparently have a greater power output than the original manufacturer claimed, e.g. the 80 hp Le Rhône 9C mysteriously becomes the "90 hp Thulin A".
