Morane-saulnier MS 410 and auxilairy fuel thanks for the 406/410

For some time I am looking for a drawing or pictures which shows the wing construction and how the machine guns were build in the wing.
After the Battle of France several MS 406 and 410 received auxilairy fuel thanks for lang range flights.
who can help me with more information pictures/drawings of the tanks and drawings of the tanks not fixed under the wing.
thanks each small detail is welcome
