CMP body type?

[No Signals]

I came across these photos online, the nearest to the camera (pic1) is a 30cwt ambulance body but the one furthest from the camera I am unable to locate a similar one online. 

I initially thought it was a Lorry, 3 ton, wireless but then noticed the obvious differences in construction and window style etc..

Any input please gents?
