Initially this model was offered only with a "Conduite Intérieure" (closed saloon/sedan) body, although a "Torpedo" bodied version was added during the Spring of 1925 [REF].
Although the "all-steel" bodied B10 could be seen as a replacement for the B2, the chassis and mechanical elements were for the most part interchangeable, and both models were produced in parallel during 1925 and 1926.
