In 1965 the company was acquired by the Seeburg Corporation of Eastlake, Ohio, and the name changed to "King Musical Instruments".

[3] H. N. White sought to expand its offerings to woodwinds starting in 1908, importing Evette & Schaeffer saxophones and clarinets manufactured by the Buffet Crampon Company of France.

Many of the earliest saxophones supplied by Cleveland Musical Instruments were made for military bands as the United States entered World War I.

[1] During World War II, the company received government contracts to assemble radar units and fuses.

In 1937 the Zephyr gained a double-socket neck that eliminated the large collar on the body tube at the neck joint and the Zephyr Special was introduced as a deluxe version with a changed bore, improved keytouches for the left hand table, and mother of pearl inlay on all keytouches.

Several famous musicians were featured playing King instruments, including Tommy Dorsey, Charlie Parker, and Harry James.

With improved left hand cluster mechanisms introduced around 1949, the Super 20 represented the zenith of H. N. White's achievements as a saxophone manufacturer.

However, new competition from Selmer (Paris), aided by the exchange rate between the French Franc and the US Dollar in the postwar era, put price pressure on the American manufacturers and H. N. White was no exception.

Some saxophones from Amati of Czechoslovakia, and Kohlert, then located in West Germany, were imported to be sold as the King Lemaire.

[4] In 1965 the company was sold to the Seeburg Corporation of Eastlake, Ohio and the name was changed to "King Musical Instruments", reflecting the long absence of models produced under the "Cleveland" and "American Standard" brands.

In 1968 Seeburg moved production to Eastlake and instituted a new round of cost-cutting that effectively ended the era of the Super 20 as a professional quality saxophone.

In 1972 Seeburg-King acquired the Benge company, which produced a distinctive line of trumpets in Los Angeles, CA, shortly thereafter moving production to Anaheim.

[1] UMI revived King's efforts in the student saxophone market, reintroducing the former Cleveland models 613 Alto and 615 Tenor, as well as assembling some Super 20s from pre-1975 stock.

Muskantor's interest in King was not merely as an investor; he had family roots in the music business and respect for the company's past accomplishments.
