Looking into the signalbox from 10cm on Macro using no flash and only the interior lamp in the signalbox gave a surprisingly good image, The first working lever can be seen pulled out from the frame and an attempt at a track diagram can be seen on the back wall above the cupboard. Now that I know the level of detail I can see with the camera I'll have to put a bit more detail in the box, A signalman would be a good start!

The box is not yet glazed as I am thinking of using thin glass microscope slips to put real glass in the windows, these are also most useful for glazing some 4mm scale buildings, locos and coaches. With plenty of uses for the 7mm scale modeller.
