theres a chap on VOC UK forums who has done a few over the years now, i'll try and find you a photo
best one i can find, he's making another one now as that one was rushed a bit for a holiday or something, the above photo being taken in italy i believe, and as you can see the paints a bit flat as a result of no lacquer, but apparently it worked pretty well.
theres a chap on retrorides from germany doing a pretty good job of a similar saloon based trailer too.
