A bit too experimental:
No ideas?
Voisin
It is not a Voisin.
At first I thought it might have been a small model of the Leyat-Propellerwagen with the propeller missing!
Is it German?
No it is not from Germany and it never had a propeller, too.
Aha - the mystery deepens.....
The picture shows a model, of course. - the original car still exists.
Up!
British?
Not british.
French?
Yes, it was a french manufacturer.
It looks like this car : 1922 Soriano-Pedroso Type P
Perfect!
Actually I expected a bigger car. It seems it is one half Spanish.
