Flaming Cockatrices
 

Does anyone know where I can find a could side view of one or more of the various Cockatrice armoured flamethrower vehicles developed by a team led by Nevil Shute Norway (the man who wrote On the Beach and many others)? All the shots I've been able to find are at odd angles, show only part of the vehicle or are partly obscured by people, objects etc. I can find no drawings at all. I 'm not too worried which model AEC based, heavy Cocckatrice or whatever.
