The Martin company was first founded in Chicago in the 1860's, but when a fire destroyed the factory, John Henry Martin moved to Elkhart, Indiana where he became a foreman for Conn. In the 1980's, King tried to market a Super 21 model, and several prototypes were made, but the market wasn't there so it was discontinued. The Super 20 was not only used by notable jazz players like Charlie Parker, Cannonball Adderley, James Moody and Yusef Lateef, but by many rock, blues and r&b bands of the 50's and 60's. The most popular and the most sought-after are the SilverSonic models, with sterling silver neck and bell. Later models would use the standard top octave key. They also featured an underslung octave key. Zephyr Specials and early Super 20's have elaborate engraving on the bell and keys, and pearls riveted to the key touches. The Super 20, which followed the Zephyr and which was basically a Zephyr with an improved mechanism and ergonomics is still one of the most popular vintage saxophones, with a market value second only to the Selmer Mark VI and Balanced and Super Balanced Action saxophones. The Zephyr and the Super 20 are saxophones with big, bright sounds that are considered the epitome of a modern jazz sound. Though they made saxophones early on, it wasn't until they made the King Zephyr in the 1930's that they made any saxophones of consequence. Later on, they moved production to Eastlake, Ohio, but it is the King Cleveland made saxophones which are considered the best. King saxophones, as well as their other brass and wind instruments were manufactured by the H.N.
