Very cool and quite rare Hohner pianet N from the mid 1960s as used by The Beatles, The Zombies, Lovin Spoonful, Soft Machine, Van Der Graff Generator and countless others. This one is in good condition and was recently serviced along with having all of the sticky pads replaced inside. I tracked down the only person in the world making accurate replicas of these which is a big part of the sound. Any questions please ask.
