Meanwhile I found the page in the net, where to download the cardstock kit:
http://www.whitstablepier.com/volks/models.htmLooking on my own intepretation for Gn15 on daylight, I have the impression, it is too small.
The dashboards look too low, compared to the scale figures, and I can´t place passengers at the benches, facing each other.
I enlarged the original kit by 220%, but I suppose, 250 - 260 would have been better.
That makes the modell very much too large for Gn15, but a good candidte for the 32 mm folks.
Have Fun
