Nice truck. I haven't seen a low-profile Dennis before. Some of the other low-profile makes are quite funny-looking (Magirus/Iveco comes to mind -- it looks like it has a duck bill) but this one is aesthetically nice.
This appliance is from 1976 and is a Dennis Delta/Simon SS220 with the registration J559(Brigade No#23)and was based at Headquarters at Ruoge Bouillon, St.Helier.
An answer to the wildly popular ERF custom chassis, which was the most common basis for British 85 foot Snorkels - starting in 1967.
The same placement of the engine behind the front axle ensured the low cab height. This was a layout pioneered by American La France in the US in 1948, and was for years the norm for almost all American forward control fire trucks, including pumpers and rescues as well as aerials.
European low profile cabs, pioneered by Magirus for Munich, usually hung the cab low down on the front of the frame, but did not include any rear seats for additional personnel.
Many years later, Morita and Hino jointly developed an aerial chassis with either two or three axles, which had a full four door five man low profile can ahead of the front axle. Examples of both their 30 and 40 meter tower ladders can be seen on this site...
