Mentioned only by Adlung, who says:

At Gröningen there is a Grossquerfl. 8' and Kleinquerflöte 4', and again in the pedal a Grossquerflöte 4', according to Mattheson's Appendix [to Niedt, pp. 172-3]; this however must be a mistake, and ought to read 8', since Werkmeister notes it as such in his Beschreibung.
