You are bidding on an extremely rare type of melodica or blowing accordion. It is constructed like the right hand (treble) side of a small piano accordion. A wedge-shaped shell covers the side where the bellows would have been, effectively forming a sort of resonance chamber (cassotto style). There is one reed block, with two reeds for every key, tuned to the same pitch – you can blow and suck to produce the notes . This is totally unique, any other melodica is blow-only. Through the resonance chamber runs a perforated zinc air-pipe, ending in a water key. The other end is intended to connect to either a mouthpiece or a flexible tube. The reeds are mounted on 4 reed plates (not a single plate per pair as in modern instruments). The reeds are made of brass and the valve strips are plastic, so moisture from blowing is not a problem.

These instruments are made in former GDR and in general these are high quality instruments made of wood. They are really built like a small proportioned keyboard side of an accordion. They have four reed plates with one reed for inhale and another reed for exhale, and what is best, they have a removable reed block, so you can tune the reeds outside of the instrument. You can open them easily just by removing four pins that attach the cover to the body.

These are the pro’s, and there is only one con: the reed plates are made of zinc and react with water, I think it’s called zinc pest, nice word, isn’t it?
