1681: Schnitger travels from Stade to Güstrow to inspect the organ and makes a report. However, he does not repair the organ.
1699: Schnitger draws up a proposal for repairs to the organ, wondering that after his first advice nothing has been done to improve the organ. He proposes to repair the windchests and make new bellows and windchannels. He further recommends changes to the reeds. In 1700 the work is done by Hans Hantelmann, probably with Schnitger's permission.
