From Ad. Gutsche, Berlin, W. 62, Kleiststr 8:
"Replying to your favor of 21st June, beg to advise that the Regal came from Camenz, Schlesien. I have been assured that until a short time ago this was used in a linen weaving town to accompany religious singins [sic]. I do not know how old the instrument is, but believe it was built sometime between 1720-1740."
