I'm going to do the British car radio in skal 1:72. I intend to use model Airfix. I have a picture from a book by Janusz Piekałkiewicz (Secret service in North Africa 1941-43) british car radio and I have a problem. This book was wrote in West Germany before 1989.Book can be bought after the fall of communism in Eastern Europe.Can any of you read his books. . There is only one picture of one side of the car. There are pipes. What material are these pipes made?Do both sides of the assembled pipe? Now I have problem with my scaner. So I will get the picture in the night.
