Hello, I have been trawling the internet trying to find specific interior details of class 121 & 122 DMU bubble cars.
I wanted to know when these units got repainted from Green to all over rail blue, where the seat coverings changed at the same time ?
Or did some units go in, have just repaint, and get their interiors/seats changed at the next major inspection/overhaul.
Any information or picture would be gratefully appreciated.
Thanking you in advance
Craig
