I think I have found a picture of this when it was first delivered to station in the Late fifties early sixties. My Grandfather was a firefigher and then went on to become Station officer at Sandown (I.W). The Photo I have seen is of newly delivered appliance with himself and crew, outside station. will see if I can find it.
I now have more details. JDL 540 and 541 were built by HCB on a Commer 21A chassis in 1952 as dual purpose (DP) appliances and carried a Merryweather 55' escape. They had a 100 gall tank and side mounted controls(just visible) Source Aidan Fisher "A Pictorial Record", p7.
