During the 1920s and early 1930s Gretsch-made guitars were sold under the Rex and 20th Century names. After that Rex guitars were made by Kay and Harmony and distributed by Gretsch.
This one here is a Rex Aragon archtop guitar made by Harmony in the 1940s and it was sold by Gretsch dealers before WWII. This particular Rex is in outstanding condition for its time making it is a real specimen of that period. The machine heads are the only things to have been replaced on it, it had lately been re-fretted and had the action lowered.
Its Loud, punchy, assertive, and has got a 151/2" wide body with carved spruce top! This thing can be compared to any of the Gibsons and Epiphones of its years.
