I was reading this thread when i learnt there was a C8AX ambulance with a slightly lengthened body. I have been aware of this very poor photo showing an RNZAF ambulance at Jacquinot Bay in 1944. I alway thought the body looked a bit long for 8/15cwt but not long enough for 30cwt.

Then a few nights ago I found this photo on the RNZAF Museum website showing RNZAF units departing Green Island for Jacquinot Bay. This led me to search this site. So proof at least one served overseas.
