Should any of our newer or younger members collect GB this website has a year by year list with images for the period 1840-2018.
No catalogue values but images are good and clear with described colours. Just basic list without going into variations.
Nice site for finding what you are missing without buying catalogue.
Link was put on other topic but felt it could appeal to wider audience.
