Following a request, and for those who are interested in such detail, here a some further photos of the chassis components.

First, the frames. Nothing particular to note really. Suspension is a centre rocking point for the front axle and twin beams for the centre and rear. Horn blocks are London Road Models cast items. Pickups bearing on the tops of the wheel treads, hidden behind the tanks and the valve gear.

Three views of the keeper plate. This has now become permanently entangled with the brake gear since the front brake stretcher passes between the front sand pipes and their support brackets. Besides retaining the driving axle boxes in their horn guides, the keeper also carries the dummy springs, ash-pan and sand pipes. The four hair pin shaped wire thingies are the pony truck side control springs. It's fixed to the frames by a number of 14 BA screws.
