An unknown German aircooled car

Sometimes it takes some more time, especially in the holiday season. During the past days I finally found some time to take up this mystery and my conclusion is that it can only be a Piccolo.
First of all the protection screen in the front entrance of the bonnet has of course the typical Piccolo shape, though the bonnet itself is non-typical for the Piccolo. Still I could find a a few examples of ca 1907 with more or less similar louvres, though the bonnet was slightly longer and fitted more closely around the frontal protection screen. The steering column arrangement with the typical downward bending steering wheel spokes as well as the lever arrangement is exactly identical to that used in the Piccolo cars. The shape of the dumb irons and wheel hubs fit well, and even the body seems to be fairly identical to the period (ca 1907 to 1909) bodies fitted on the Piccolo.
Circumstantial evidence is the fact that Penig is not too far from Apolda (slightly more than 100 kms) and that the owner was an industrialist, who, besides being a client, could even have had a business-relationship with the Piccolo factory.
Though dating of the car is difficult because of lack of similar examples, my idea is that we see a transition model between the earlier model with the curved dash and the later models with the more conventional bonnet, with a likely production date of 1906 or 1907.

Thanks for the answers. This bonnet is untypical for Piccolo. Meanwhile I think is could be NOT Piccolo. This picture is from about 1910.

According the future shape for the radiator, I think, that is a 1905 " Wanderermobile " from Wanderer-Werke, with Two cylinder air-cooled engine.

the radiator definitely is not from a Picolo ( they had round ones) , maybe its an early Sperber?

Well, this is definitively a beautiful shot of an early (most probably) German car. Yet, I have my doubts, whether it's an Apollo, as Christian suggests.

Indeed, the car bears a certain resemblance to the aircooled Apollo cars that were built by the Ruppe & Sohn AG in Thuringia and were equipped with an engine cover starting from 1907.

However, the rather small air intake appears odd, as do the vertical cooling ribs (?) in front of the bulkhead. Furthermore, the car in the picture lacks the large flap on top of the engine hood that could be opened, in order to improve the airflow around the engine.

Hence, I could imagine that this picture shows a car from another German small-scale manufacturer from the pre-WW1 era, most of which have fallen in complete obscurity and are hardly documented in the automotive literature - which is a pity.

In 1906 Piccolo got bonnet and a dummy radiator according to H. H. von Fersen.
The louvers are very characteristic for the Apolda company's products.

It certainly looks very much like a Piccolo! I am not familiar with this type of bonnet, but a lot of details says PICCOLO. It seems to have the longer wheelbase, like the cars produced 1907-1910.
