I'm ashamed to say I didn't get a piccy, but there was a great thumper out on the field. It was an army issue BSA unit single. The paintwork was the original army green. What cheered me up was the fact that it was obviously a well-used bike, it had a neat little single wheel trailer with an ammo box as its body. The owner had painted the bike's registration on the rear of the box.
What a nice effort. It looked to be a good little hack.
