Started this about two years ago when I had the luck to get a parts lot in an online auction. I always liked the vintage ploprof, but at a price range about 4000 - 7000 $ nothing for me. All parts are still easily available except the case. So why not build one myself... Based on various technical drawings and original parts I measured the important interior and had this made by a friend: To get the basic shape the case was cut out with water (with some abrasive and pressure added :-)
