This post from Life In The Past Lane inspired me to dig out the two useful wagons that came with the Airfix Waterloo Assault Set.
Not sure I've ever used them on the table top, but I plan to one day.
They were assembled and painted a long time ago.
There was other stuff that came with the wagons. I've got the wood pile somewhere and the log barricade. Some sacks and barrels are around and in use as well. There was a funny wheelbarrow thing as well, mines half painted or rather half the paint might have peeled off.
