Vintage Kay "St. Louis" Harmonica in Key of G | Ornate Engraved Blues Harp with Original Case

Channel classic folk and blues vibes with this charming vintage Kay "St. Louis" diatonic harmonica. Stamped "Made in Korea" on the back of its case, this instrument likely dates to the 1970s or 1980s, an era when the historic American Kay Musical Instrument Company transitioned its production overseas.

This beautifully designed "blues harp" features polished metal cover plates decorated with ornate, scrolling floral engravings and the prominent "St. Louis" model name. Stamped with a "G" on the right side, it is tuned to the Key of G. The harmonica features a traditional sandwich-style construction with visible brass reed plates. It comes perfectly preserved in its original navy blue vinyl snap-closure case, which still bears the gold-foil Kay logo. Whether you're a folk musician looking for a pocket instrument or a collector needing a stylish vintage display piece for a music room, this is a fantastic find.
