huh?! am I just stupid and didn't see all your posts all the time, or is the date-time thingy all messed up again?
But yeah, tristan you were right, it is the NSU TT (see image)

Still very popular in german mountain-climb-races. They look awfully funny with their hood open (it's in the back for those who don't know)
