Just found this on a german forum. A guy from the Netherlands has bought a 914-6 that was originally owned by the dutch Police "RIJKSPOLITIE", and now he's going to restore it to the original specifications.
He put the info on a homepage, unfortunately only dutch text.
see here
At the bottom of the text there is a link to more photos and additional info.
thought that might be interesting to some of you
