I have one of these myself.  It is part of a genuine Westfalia side tent.
The tent clips onto the poles from underneath and can be removed for 'awning
only' use. The tent half has the Westfalia logo on it.  Not sure if it was
ever offered without the accompanying tent (as you have it), or if the tent
part of yours was 'lost' along the way.
