Lang,
I think this vehicle has now changed hands - you may be aware of that ?
Col's T was one of the earlier brass models of the type that was issued to the Australian Light Car Patrols in 1916. Before that date, I think these patrols were issued with an amalgam of diverse vehicles. These brass Ts were replaced by 1917 Ts, in Palestine on 11 Dec 17.
There is a very good website on these vehicles under the heading of 1st Australian Armoured Car Section at

As the prelude to these writings indicate, much of this is taken from a manuscript held by the AWM and submitted by Captain E.H. James called "The Motor Patrol".
The British had these same vehicles too - in fact they were manufactured at Ford's Manchester factory and appear to have been produced to a War Office design. Though I've no proof of that (I wish I did have - the IWM can't/won't help), the configuration of all the vehicles I've seen on the AWM collection, is so similar that there's probably little doubt they were a WO designed body.
Are you looking for photos of the early or late Model Ts ?
