This is something that I wrote up for the NGS Journal a few years ago. It’s also the only modelling project I seem to have any photos of on my phone.
It’s an SJA scrap wagon, based on a Farish MEA. It’s a good project for someone who’s nervous about hacking up an RTR wagon because you don’t have to hack anything: you just assemble the door on each side, attach it to the body, add a couple of deflector plates and voila!
I’m pretty pleased with this, although the painting could have been better. The lettering, such as it is, was provided by Precision Decals.
In the interests of learning how it’s done, here’s another photo.
