H.B.H. - The Emperor
Clearly this caravan was one of the finest in the H.B.H. range as I found this booklet of photographs obviously prepared as a hand-out to prospective purchasers. Even though the booklet was fairly amateurish in its production, the caravan certainly was not, demonstrating excellent design and quality workmanship throughout.
It seems that you entered via the kitchen situate at the front of the caravan that was separated from the lounge (that doubled as a bedroom) with a further bedroom to the rear.
