M201 - wing mirror / rétroviseur
M201s left the factory fitted with one round wing mirror much the same as found on the original WW2 Willys MB. Whilst these were still just about suitable for road use during the 50s & 60s they were eventually replaced (probably during the 80s) with a larger and more practical version.
The photograph above shows the larger rear view mirror which was sometimes mounted on both sides of the jeep. Look carefully and you will notice that it has a black plastic surround and the mounting nut has a black plastic cover to comply with later road law standards aimed at reducing injury. In practice, many of the plastic covers appear to have fallen off in use.
