Thulin went bankrupt in 1924, but the company was reorganised in 1927 - the Type B was a new model designed by the Swedish brothers Axel and Per Weiertz. The Type B used a 1.7 litre 4-cylinder engine in a very low slung chassis with 4-wheel brakes. Only 13 were built before Thulin were permanently forced out of business early in 1928 by the continuing availability of low priced American imports as well as the immediate success of the first Volvo passenger cars in 1927.
