C60X 15000lb winch details needed

[cliff]

I am doing a model of the #4 (Aust) workshop/machinery truck built on the C60X chassis. Now Barts book says that these were fitted with the 15000lb winch behind the cab and I am after some close up pics of this winch and maybe the measurements of it if Possible.

Also where was this winch cable hooked up to? I know the gantry had a chain block and tackle so was this similar to the GT winches?

The 'dog boxes behind the cab and in front of the main rear body. What were these used for? I know one would be the spare wheel carrier but the others, including the two small ones sitting on top?

Any help would be appreciated
