The body was obtained second hand as far as I am aware the Airfix/Dapol/Hornby bodies are all the same.
Anyway there are plenty of things I have added such as new handrails and buffers from Alan Gibson, there is still plenty more to do before a repaint in to BR black, since the photos were taken I have reduced the thickness of the front spashers although this will only be possible if you model in P4.
The HighLevel Chassis kit really makes the model It is fully compestated and has full dummy inside valve gear and slidebars etc, and the way the motor and gearbox is designed leaves the cab free to add as much detail as needed.
Here is another photo of the chassis showing the inside valve gear betwwen the frames.
