Dug this late 1970s Airfix 14xx out the other day. I recall it was one of my first weathering exercises around 1980 using airbrushing and dry brushing. I also added etched cabside plates.
The body with separate handrails and other detail was well ahead of its time for UK outline back then. I think it still looks pretty good. Sadly the chassis is quite the opposite, almost 40 years on it's s very much a non-runner. Might be worth putting something else under there from Comet or High Level in due course.
Here is the little locomotive posed on Brew Street, my recent 'nano' layout.
