It can be the smallest details that need adding to give authenticity to “off-the-shelf” products to really bring them to life. We laser-cut track circuit diamonds and sighting boards for Chris Bull to complete his Dapol O-Gauge signal, which he has then weathered before fitting to his layout.

The quadrant for the sighting boards took a while to work out; the pivot is the rotation point of the signal arm so it’s not quite a full quadrant, being off-set.
