NOS in the original box.
Mercedes Avog 2 speed blower motor and fan for the W180 220S, W128 220SE and other models. The lower end Ponton used a single speed fan.
The diameter of the housing is 4.5 inches and also the depth to the motor end.
The 2 speed motor is no longer available from Mercedes.
I have a couple others listed in different size single and 2 speed.
