OK, so a while back I bought a Matchbox car of a 1974 Volkswagen Thing for a dollar, just to see if it was the right size to be a Kubelwagen for background scenery in 28mm WWII gaming. I measured it, and it is 1:58 scale while 28mm is normally considered 1:56 scale (thank you, Warlord Games for standardizing this!) So, close enough for a scenic item, am I right? I know the front end is all wrong, but it should be fine for a bit of background color.
I have more pictures and commentary on my blog at
