This is the later design cab, with a four door configuration, unlike the earlier ones, which had two central doors, and are illustrated many times on this site.
These were originally requested by London Fire Brigade, who also purchased several dual purpose appliances from Merryweather and (I think) David Haydon with the same style cab.
Apart from better maneuverability due to a shorter wheelbase because the front axle was further back, it also made cab access easier for the driver and other crew members - if any.
The 1966 registration suggests that this was probably one of the last of this design, as the AEC Ergomatic cab was introduced around this time.
This is NWY490E. 1967 AEC Mercury based at Harrogate. Picture taken outside the Conference Centre. New to West Riding fire service, passed to North Yorkshire on local Government reorganisation. Went as a reserve TL, disposed of in 1987.
