If you're interested in going to this, check out the German Typ 3 group website at http://www.typ3.de/index.php?page=jahrestreffen-2017 .
They have a form (Anmeldung) to fill in for camping, or caravan etc., and a graphic to download (Label) if you want to make a window sticker.
Ralph is the local organiser. Many of you will remember him from his visit to Stanford Hall when we had the 50 years of Type 3 display.
