Having got back in the hobby I decided to get some back issues of the SE mag and managed to get almost a full set from guy in Cambridgeshire (via the Forum) whilst down there picking my motorhome up. Looking through these I came across an article on the "Hydraulux" pump I recently acquired. According to a previous employee of the manufacturer, "Craven's" there were only about 16 of them ever made, so it is a bit of a rarity!!
