Looks like there might be some kind of logo or insignia or emblem in the middle. For some reason I want to say Oldsmobile or a Chrysler product.
The body and wings is Ford 32 fordor and the grill shell is a Delage (French make) All the photo of build is here http://http://www.rods-customs.com/forum/viewtopic.php?f=36&t=7765
Many thanks for identification of the dashboard insert,i have another question,what is the origin of heater control? De Soto?
I think this link might work better. I like your thinking! Are you using the Rover's DeDion axle? I know it's a duplication of labour, but those of us whose French is at best dubious would also appreciate a build thread Edit: I see you are using the Rover axle. I've taken the liberty of posting one of your photos on the DeDion axle thread. Welcome aboard, Hispano!
