Opel Olympia- roof rack

I wanted to make the mat for driving out of mud, which was often fastened to the bumpers of the Wehrmacht cars on the eastern front. I didnt wonna cover any of the vehicle details, so i decided to build the roof rack.
After 3 days of trial, and error i finally achieved the acceptable shape.

Wooden slats made from styrene.
I will place the mentioned mud mat on it, along with the cannister, luggage, and possibly the wicker basket.
