Gretsch hadn’t yet adopted the Cadillac-inspired Eldorado name for the 6040 model shown in their 1952-53 catalogue. This 1953 6040 looks so close to the guitar shown in that catalogue that it possibly could have been the example that Gretsch depicted.
Noteworthy features include the crossed peghead inlay with “Synchromatic” inscribed on the jagged-design crosspiece, mother-of-pearl “slashed humptop” fretboard inlays, gold-plated Grover Imperial tuners with flat-surface stairstep buttons, and an abundance of multi-ply binding almost everywhere, including around the f-holes. This Gretsch 6040 is a fine full-body, 18-inch archtop guitar that any jazz guitarist would have been very proud to own and play during the 1950s (and still today).
