I have a Silver fox C class and thought the exhaust holes where in the middle where the small rectangles are.
So i made two holes there and filed the sides flat. I have posted a picture of it below.
I was watching a youtube video from ITG starting their C class and the exhaust smoke was coming from the middle two holes.
Perhaps this was changed when rengined.
Great work, nearly there.
I don't think i have ever seen a picture of a GSR loco in that shade of green.
maybe if someone has such a thing they could post it up to have a look at.
One of my favourite liveries, simple but beautiful.
i can imagine your reaction when you opened the boxes for the first time, it must have been like Christmas.
