Here is a section from the late Queen Elizabeth, the Queen Mother's obituary in the Guardian which might help.
Whatever time she got to bed, a curtseying maid would tap on her bedroom door at 7.30 the following morning. The maid would enter carrying a tray with a bone-china teacup, pink roses and a copy of the Racing Post, and place it next to her bed. After an early-morning bath the Queen Mother would walk to the breakfast room, where she would sit down to a plate of fruit, toast and a free-range boiled Buff Orpington egg.
