Updated through online information from Neal Campbell. -- I understand the statement that the organ has been slightly altered, but it's in almost perfect playing condition. I've played it several times this season. Tuning is a continuing issue, but it all works just fine. The real thing missing in the description is the fact that the Positiv is located on the opposite side of the chancel, exposed on a chest that is hung from the ceiling of the side chapel! It is not in the case as the description sort of implies.
