So I've been getting on with the chassis of 2047 - and also getting it wrong (again)!
The original WHR saloons built by Winsons were very modest and keep all their gubbins covered up behind large panels which ran almost all the way along the underneath between the two bogies.
Quite literally a case of 'nothing to see here!.
Since then progressive designs of the carriages have opened everything up and all the brake gear and other stuff is on show, which is bad news for the modeller when the carriages sit so high on their bogies and there's so much daylight underneath them.
So what you can see here are representations of the vacuum cylinder and the reservoir along with the boxed areas which contain, among other things the fuel tank for the heater and the batteries for the electrics.
I had still to add the brake gear fashioned out of brass when I took this picture.
I have also since discovered that I've once again made the mistake of using 2046 as a guide and making a wild assumption about them being identical.
In fact it turns out that the longer of the two panels, nearest the camera, is cut back on 2047 allowing sight of the brake gear from both sides.
This is easily corrected at this stage, but it's annoying all the same.
