AB Thulinverken was a company in Landskrona, Sweden, founded in 1914 as Enoch Thulins Aeroplanfabrik by the airman and aircraft designer Dr. 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.

Notes

^ The Thulin A's Gnome Omega was sometimes described as a Thulin engine. Although Thulin built Le Rhônes under licence, it is unlikely that Thulin built Gnomes since he didn't use the Omega on any other aircraft and it was outdated when he started making engines.
^ 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".
