Fuchsschwank German Fuchsschwanz German Noli me tangere Latin
In describing this unlikely “stop”, whose name comes from the German “fuchs” (fox), “schwanz” (tail), and “schwank” (joke), I could not possibly improve upon Wedgwood, whose entry reads as follows:
Regarding Fuchsschwanz, Adlung writes: “Of course the name is not written on [the stopknob].”
See Vox Inaudita.
Examples
Noli me tangere; Domes St.Maria (cathedral), Riga, Latvia; Walcker 1883 (restored 1983). This is actually a Pedal to Great (not Great to Pedal!) coupler.
