A variant of the 2-2/3' Twelfth, mentioned only by Irwin, who claims that the stop can be made from �chimnied pipes�. However, such a pipe form would yield a flute tone rather than the soft diapason tone implied by the stop's name, and might more appropriately be called Rohrnasat. Examples None known.
