I have recently found a photo on the Internet of an Alvis Stalwart modified for crash rescue work on Gan. The vehicle, 00 AG 79, appears to have some form of pump and water and/or foam delivery system in the load compartment: presumably water and/or foam tanks were also located there. I am assuming that this was a local modification and that drawings and/or photographic records are likely to be scarce or non-existent. Is there anyone here who served on Gan and who remembers this vehicle, or who has additional photographs of it? Any information will be gratefully received.
