Regarding the American rear lights mentioned, I would assume these have been fitted to provide stop/tail and indicator in a 'military' configuration.
Originally both models were fitted with a single early pattern rubber tail light on each side. I followed this original configuration but had to fit two each side to give all required road legal lighting.
Just noticed the auction vehicle is fitted with the wrong rear bumper. The C11AS was fitted with a bumper of the same profile as the front, which was to offer protection for the spare wheel and carrier. The C11ADF however was fitted with a straight bumper as the spare wheel was stowed in the rear body space. Tow /tie down rings were only fitted to the AS model.
