You did very well to trace this car Barrett as I'm blowed if I can find anything about it - not even the site where I first found it!
You are of course correct in that it is a VW Special built by the students at the Karosseriebaufachschule Kaiserslautern (which I believe means the bodywork specialist school in the city of Kaiserslautern).
I did ask for the date of build in my original post, however, so once you give me that I'll be able to award you the point and put this one to bed!
Locked for your reply!
