Vintage Kay Musical Instrument Company Headstock

This image displays the rear headstock portion of a vintage Kay acoustic or electric guitar. The most prominent feature is a rectangular brass or gold-toned metal identification plate riveted to the wood. The plate includes the 'Kay Musical Instrument Company' text, their stylized 'K' grid logo, and a stamped Instrument No. B-1170. The headstock is finished in a dark, glossy black or deep espresso nitrocellulose-style lacquer. It is equipped with premium Grover Rotomatic tuners, which are non-original upgrades for most Kay models, featuring their classic chrome-plated teardrop buttons and 'PAT. PEND. U.S.A.' stampings. The presence of these high-end tuners suggests a player-modified instrument likely dating from the 1950s or 1960s, a period when Kay was a major American manufacturer based in Chicago. The condition shows minor surface swirling and light dust consistent with age, but the headstock appears structurally sound without visible cracks or repairs. The metal plate shows some light oxidation and character-building patina.
