Question Author
Thank you dinkypuzzled for your thoughts, which have certainly given me something to work with.
There are 46 clues/questions in this quiz and the second clue was: Plural letter plus a deep hole - which gives S-AND-PIT, so I do not think there is a connection with the clue on which I am stuck. I have been thinking around the second letter of the alphabet, but nothing dawns, so I like your suggestion of TUMBLER. I currently still have no idea as to what the remainder of the clue refers.
Once again, thanks for your time and trouble, and to anyone else who might contribute.
