Welcome Jan. Sounds like a project, but a worthwhile one. If I may be permitted to offer a bit of advice (learned form years of restoring vintage cars) do something every day, even if it's only make a phone call. Even if it is just freeing off a nut and bolt or some similar small task. Regular small amounts of work is the way foreward and will get you there in the end. Lets have some photos now and as you work through the restoration. As you will have seen on another post today about an EribaCar, there is a specific Facebook group that might be a good resource for you...
Best of luck!!
