I've since found out at that time it was probably 26041, but having checked the finer details between locos in the same livery, my CJM model will have to stay as 26038. Still, not complaining - it is a beautiful model.
I'm sure these are going to be great models, although I have a CJM 26 already. Since Dapol have announced the exact same number for the red stripe version, I might have to get mine changed!
Can anyone remember which was the Railfreight Red Stripe liveried 26 which always seemed to be at Carlisle around 1991/92?
