Ratio signal box - the crit'

Well it's done. Sort of. Not being able to run with anything as designed, there are obvious changes and a glaring problem that looks worse here than in real life.
The kit comes with stone steps - I thought his was a bit visually boring so diddled around with the 'extra' bits that come on the sprue. These are there as they are common with the kit for the larger box. With a bit of cutting and some 20 thou strip it's possible to knock up a narrow balcony, though this would benefit from a support or two.
The kit as bought goes together well if a bit fiddly. The fail is the guttering and down pipes. The gutter pieces are shorter than the roof by about 3mm. There must be a reason for this, but I can't quite work it out. Worse are the down pipes - beautifully made and designed to stand out from the building. The problem is that it's not enough. Any real pipe in this situation  would have a swan neck to bring the pipe into the building. When I summon up the bother I'll replace with some 1mm rod suitably curved and less jarring. The foot board is loose and would need adjusting in situ.
