I midified one of these consoles, a Wicks pipe organ console of about 1950 vintage. It was my prototype Hauptwerk organ.
The stop tab/memory capture linkage is poorly designed. The aged plastic tabs easily break at their juncture to the angled metal mounting brackets. Generous mounds of epoxy glue is a neither a preventive nor a repair agent.
Purchase this organ with the idea that it is only a key board device. Make all stop selections via a touch screen monitor.
Keep these facts in mind if making a bid for the item.
