Teak wood casing - oiled.The instrument is from the initial series and has FACTORY Midi (see photo). 
I can add a stiff or comfortable case. 
Instructions in English. 
Additionally, the filter potentiometers were thrown outside. 
Very good condition. 
Everything works, switches. 
The instrument has been fully serviced. 
Only selling because I'm making another one with knobs for outdoor editing. 
It is one of the pampered and carefully preserved gems in my collection, but I simply do not have room for two identical pieces.
