There is mention there that this is a conception of what the car is to look like, and might not be exactly like the final product.
The hood ornament is one of the similarities to the ford model. I didn't realise Daimler's had one like that too, but then, not being much of a car afficionado, I am not sure I have ever actually seen a Daimler.
