Rosie , I'm sorry , but that entry only goes to 1967, we all know QE2 came after this date, as ever; you are ahed of the game looking into Royal Mail . com (I was going to do that next week or whenever!!) However it's probably completely out of topic here, but I was looking up the R M S thing & came across this c/o' QE2 ' a ship for all seasons' ,David R Hutchings, p23, '' In the Mary and the Elizabeth the kitchens, being so low in those ships, had a garbage shute which opened to the sea through the bottom of the ship and down which the rubbish could be jettisoned.There was no such shute on the QE2 so garbage would have to be bagged and manually thrown overboard. That is until a special door was cut into the side of the ship, disguised behind the large' U 'of the red CUNARD logo painted onthe superstructure at the fore end of the Quarter Deck''. Funny what you find whilst looking for something else
