I remember firemen at Nottingham City central fire station grumbling about the very steep and narrow rear cab steps on this appliance, and about the fact that its pump was hard to operate with the escape ladder in place. They had had the same problem with its predecessor, a Dennis F12 with a rear mounted pump - but at least it had had a side mounted control panel for the hose reel pump, which was what got used most often...
It shared the appliance room with a nearly identical AEC-HCB water tender, an AEC Merryweather TL, a Bedford CF window van, which served as a command van and a rather unusual Leyland Mastiff ET. This was the only one I ever saw or heard of.
