Was being driven to our new base last week and stopped beside this on the road. Not the best of pictures I'm afraid as I only had my BB to hand but any ideas? Looked home-made or wagon based but raised and hacked about.
That looks to be the closest match so far. Didn't manage to get a good picture of the lights as something was blocking my view but they were much bigger than in the picture so I guess that might explain all the filler.
