A very interesting and useful set of pictures, I have an EHU Austin chassis (but fitted with HU pump), interesting to see in one pic the spare wheel is under the chassis rails at the back, but in another this is a locker, also mine doesn't have the lockers under the doors
There were relatively few EHUs, rated at 1100 IGPM, compared to the HU (on similar chassis with similar bodywork) rated at 700. The AFS and subsequent NFS trailers pumps were of varying capacities, up to 500. The EHU had a higher engine housing than the HU, larger hard suctions, and six delivery outlets, rather than four on the HU.
