Audsley lists this stop with the following description: The name given to a labial metal stop, of 16 ft. pitch, the higher notes of which produce tones similar to those of the Traversflöte, 8 ft. According to Wolfram (1815), an example exists in the Pedal of the Organ in the Chuch of St. Bonifacii, Langensalza. Wedgwood also lists it, but says only �see Flauto Traverso�, then never mentions it again. The suffix bass was often used by German organ builders to indicate that a stop belonged to the Pedal.
