Evening Roly,
Thanks for comments re: my weathering. Which reminds me-I better fire up the airbrush again soon and finish a few bits off.
I would have imagined that the handrails would have been green on the bodywork and black around the smokebox. However, I'm not an expert of this period of GWR locos and would imagine a 'PM' to Mikkel would answer your question.
Hope that helps Roly, and look forwards to the next instalment.
Cheers,
Mark
