I built this back in 2008, as a way back into modelling after a long (even by my standards) lay-off.
It's a plastic kit of a Jung RK20B 4 wheel shunter. It was also my introduction to airbrushing, using a newly bought Badger 150.
The body colour is Tamiya XF-5 Flat Green, I can't remember the frame colour but it's probably Phoenix Precision Dirty Black acrylic or Tamiya Nato Black.
I used Tamiya XF-3 Flat Yellow on the buffer beams, and the wasp stripes are Impetus transfers. Varnish is Phoenix Precision Airbrush Enamel.
The end guardrail was soldered up from brass wire as I decided the plastic moulding was too heavy. I also replaced the bonnet side handrails with wire.
I meant to straighten that coupling (Smiths LP10 3 links) before taking the photo!
Buffers are brass A1 Models 18" jobs.
Can interior;
Power comes from a 35mm wheelbase Tenshodo spud, converted to EM with 14mm Romford/Jackson disc wheels, the bogie being held in place by friction. I had to move the sideframes out by a few millimetres to clear the wider gauge. To add some much needed mass I used lead fishing weight, glued in with PVA. No nasty side effects so far!
It's quite a nice kit, and I'm still happy with the build although it's never seen use. The paint finish is pretty good and it fulfilled its function of getting my hand back in as well as being my first attempt at spray painting.
A 4mm scale kit of a Jung is an odd choice for the UK market but I believe the loco was chosen for the possibilities for kit bashing, there are certainly many of these running as 009 locos. But, I still think Knightwing missed a trick by choosing a German prototype instead of something British, a Ruston 88DS would have been a far better choice in my opinion.
