Thank you everyone for your replies - it has been very helpful. It seems the CSX3050 was originally painted for Gulf
Oil? So is it Gulf
Oil Orange?
The swatch of colours shown in the other thread (thx cycleguy) does not name the colours, but its still good to see.
Thx again, I really appreciate it. I will now hunt down as many pix of CSX2409 and CSX3050 as I can!
