To be fair wannabay I have no idea, the previouse owner is a car renovator by trade and he did all the mods in about 2000/ 2002, I bought it as is ,just over a year ago and its been a pleasure to own.
I never knew it as a true Danbury and the add was written by Gary at Cool Campers, ( who probably does know a genuine Danbury ). It might be his way of saying "not genuine".
It has working gas fridge, two ring cooker, electric water tap, rear belts, and three quarter bed, to me its all up together and looks period without looking dated,,,, if that makes sense.
