The first picture with the light beige is the original colours and was fitted to the 17 seater First aircraft plus a couple more of the 14 seaters before it was changed to the blue/ grey colour scheme.
I’m doubting myself now, I know the original one had a beige carpet but was changed to to being impractical.
The picture here with the beige carpet is a 13 seater RR aircraft and they came even later.
