Skip, in those days customers could order either only a running chassis or a complete car with a standard Mercedes coachwork. The factory coachwork always had cycle wings and looked like this:
This is the displayed original SSK in the Mercedes-Museum in Stuttgart.
Of course it is possible that owners modified their car later on, f. e. to make it road legal in their country.
Customers who ordered only a running chassis felt free to fit any bespoke coachwork to their chassis.
Your pictures show some examples. On top ist a coachwork by Murphy of California. The second and the third could probably be French. The fourth shows a SSKL like I built.
You can recognize the same mesh radiator guard on this SSKL as on my photo
