There was a series of recordings by Alf Linder on Westminster Recording Co., played on the Organ of Varfrukyrka in Skänninge, Sweden, made in 1772 by Lars Wahlberg and Anders Wollander."
Interesting that Buxtehude played on organs that were NOT well tempered.
I have heard/read that old sacred music loses something significant when played on well tempered organs.
Of course the limitation was that old organs were limited in what keys they could play.
