Urs: This discussion has lead me to realized an error in my thinking ( and in how Lilypond works ). My thinking was that if \override TupletNumber #'stencil = ##f stopped the number from being printed, then \override TupletNumber #'stencil = ##t would cause it to be printed.
I shall study Mr. Long's suggestion, yours, and the manual to correct my knowledge. Thank you for helping me learn and use Lilypond.

So when you afterwards say #'stencil = ##f there isn't an object anymore LilyPond can refer to. You could however assign a new stencil with that command. Maybe Jim Long's suggestion works (don't know). If not you should either try to achieve the desired result with an other method than removing the stencil or look up how to (re-)add the appropriate stencil instead of your second example line.
