Early Castagnari Sander DG 3 voice MMM, 21 button treble 12 bass. Antonelli tipo a mano reeds. Fourth button start with standard low notes. It has a stepped keyboard with traditional wooden action. There is one stop on the treble end to control the third M reed. No bass stops. It is only on the market because of the owners poor health. Hard case and straps are included. I have completed a full reed overhaul with new valves, new wax and tuning for treble and bass reeds, so this lovely old instrument is now set up for many years of playing.
