Instrument is in reasonably good condition and is playable.
Soviet era Ditonic accordion (70's?), but not in the european style.
The notes are the same in both directions (like playing the C scale on a piano accordion) including the basses which are set up like a button accordion but are also the same in both directions, the basses and chords all reflect those used in the key of D.
