Coppendoff German? Copendoff German?

Adlung lists this stop with the following description:

Coppendoff 2 and 3 is [found] in the Kneiphof (or Cathedral) at Königsberg. I know nothing really conclusive about it, but I surmise that it is the same thing that others call the Koppel, if by that [term] is understood a stop that consists of two ranks of pipes, in particular the Rauschpfeife.

Wedgwood also lists it, but says only “Coppendoff - 2 ft.; 2-2/3 ft. Königsberg. Perhaps Coppell Döff.”

See Coppel.
