Say what you like about the quality of Kay guitars, but from 1938 to 1968 they were made in America, specifically in its Chicago factory. The company was dissolved in 1969 and the "Kay" brand was acquired by an affiliate of Teisco.

[RIC content: Kay also made some of the bodies of Rickenbacker's early Spanish guitars, such as the S-59 (p. 50 of Smith book).]
Similar story for The Harmony Company, which made its stringed instruments in the US from 1892 to 1975, also primarily in Chicago. The Harmony name was later acquired by an importer for "reissue" Asian exports.

Harmony used DeArmond pickups, made in Toledo Ohio, in its electric guitars. Some recording artists today use vintage Harmony-made instruments and value the sound of the DeArmond PUs.
