Just some models.
For one point, please respond and identify the car these models led to.

It looks the Brütsch design for the KLEINSCHNITTGER F 250 S
After my previous reply I've found a picture of that car that shows the model F250 C in the front plate, it's a coupe with four seats. The S has different grille and only seats for 3 across.
I'm not sure about the Brütsch part, although it looks like it.. But you are right about these cars being Kleinschnittgers, and they are a F 250 S and a F 250 C. ;D
One more point for you.
