Splodging various browns around on the back proved that Alan, like me, knows that GWR Brown and Railmatch Underframe Dirt are basically the same thing. The wonderful Great W painted things in dirt colour!
Anyway, with a bit of careful brushwork I browned all the plastic, except for the drainpipe which was painted weathered black. Not sure if this is correct but to be honest I was fed up with all the brown.
The results look very nice to my eyes. At the moment I don't have anywhere to use the box properly so it's joined my collection of models - a rare item built by someone other than me in here.
For the photos, I borrowed the L&WMRS O gauge layout "Kimble", popping the box in a field near one of the signals. I think with a suitable name board and some bedding it, it would look very nice here.
Thanks to Chris Nevard, Iain Robinson and Alan Downes for their contributions to this enjoyable project.
