Signal Box.

 Now for the tricky bit. The window aperatures and clapboarding have been made from various plastic strip and sheet.
This was then fixed to the superstructure with Cockpit Glue which seems to adhere most things. I intend to use this product to fix the etched windows to clear plastic as it dries clear.
The lower floor door still has to be opened out and the brick frames fitted with lintels and window sills- more brickpaper!
