Antique Toy Trucks

I have this antique toy truck. Totally true, but I can not know how much it is worth. Hopefully there is a fan of toys out there that can help me. I can only say that there seems to be a molded truck manufactured by Schuco Shell. Prior to the 60's made in Germany.

Above is the site that shows a photo of the truck, but the covers are silver instead of red. I guess the truck in this picture is a newer model, but it looks exactly the same thing. Any help would be greatly appreciated. What I seek is above its net worth.

about 40 euro. It is not that precious, hope u do not expect one million.
