FO 1980 rolling stock


Does anybody have or know of photos of the original interior of the Furka-Oberalp SIG type 2 coaches? Especially the walls in first class are unknown. These were:
A 4063-66
ABt 4155-59
ABt 4195

I could find a photo that shows the colours of the seats (red in smoking, green in non-smoking) - from outside.

Also of interest would be if the seats were exactly the same in ABt 4155-59.
