Signal Box innards!

Having a rare hour to kill, I thought that it was time I stuck the roof on the Signalbox.
But- no interior detail had been fitted although it isn't possible to see as the back faces those viewing.
So a piece of channel-plastic- had a dozen holes drilled in it, and some plastic rod stuck in these with MEK. Then some black plasticard to make the shelf and some offcuts to give a suggestion of instruments and an hour is up.
Just got to paint the levers and the instruments and the'box roof can be securely fitted.
