I'm trying to restore this. I know, I know

But the chassis is already nearly completed, the original engine is running, gearbox fixed /rear axle still making problems though!/, have found all the needed bits and pieces except the wipers system and a couple of dash switches. So here comes the rust challenge. And to make things worse, it is not only rust, but rot, too. Have to build wooden structure inside. Fortunately have all the bits, can't be used any more in the car, but perfect for pattern. As a model, it's a 1940 built Mercedes 170V, the cheaper Mercedes of the 1930's.
