Hi Ales,
I'm familiar with the pic
Some general info.
Quote (basic summary of info)-
These wrer mainly for protecting airfields, ammo dumps and fuel dumps. They were built on the QLD chassis, the basic body of the vehicle was similar to the QLD (GS) Special (metal body), but the body was slightly longer making the vehicle 20ft 2in overall, The QLD GS Special was 19ft 8ins. The body also had 4 lockers cut into the front part and a shallower tail gate flap. The main equipment consisted of a 200 gallon water tank mounted centrallt in the forward end of the body together with with a hose reel mounted between the body and the cab. There was also a pump driven from the pto and this was controlled by remote engine throttle. This basic equipment was used in the first aid role of the unit and could be put into action pretty quickly.
For larger fires a trailer pump was towed, usually either a Coventry Climax or Godiva pump. Fixtures were provided on the vehicle to carry a 30ft extension ladder which was hung from the tilt superstructure and protruded both fore and aft. Side lockers were provided to carry suction hose and all the necessary nozzles for the trailer pump together with various types for fire extinguisher.
To make it very destinctive it carried a warning bell, which was a compulsory item or all fire fighting equipment and a large board as shown with ARMY FIRE SERVICE on it.

I've seen a picture of a Merryweather cable operated fire escape ladder mounted on a QLC Chassis, prototype for what went into production as the Simon Observation Post.
