The first one. A piano that works by air pressure, wooden, over twenty years old as they say, made entirely of wood, inside an air bag that is manually compressed to produce sound. It needs simple maintenance like cleaning, tightening screws, and so on. It works well now, but with maintenance, its sound and performance will improve. It's suitable for a museum. The second one is brand new, like new. The second one I ordered from India, brand new. The reason for selling is that it arrived different from what I ordered; the model was different. I only used it two or three times. For offers. Selling both together. For offers. Selling both together. For offers. Selling both together.
