I can see in the second photo there is casting for the two forked ends of the Clayton front axle.
In the third photo is the outer pedestal casting (I need one of those by the way) and flywheel and probably the base and cylinder for a Stuart Victoria engine, and also there are the two rear axle bearings for the Clayton, the dif centre is either for the Allchin Royal Chester or the Clayton, they both used the same dif.
As already stated, the Y spoked wheels are also for the Clayton, I am guessing the boiler might be as well.
