This is one of very few O Gauge P.O wagons I have weathered – it is a Slaters or similar with pre-printed sides. The plank joins are not as deep as some other brands, but I managed to get some semblance of shadowing in the joins – sadly this model has no planking on the inside and it shows and looks flat! I was given this to weather many months ago, but slowly catching up. If this was my wagon, I would definitely give it a full coal load.
