Vintage Antique Pre-war Hohner Marine Band Model 365 14-Hole Harmonica. Key of C. 14 holes for extended range. According to Hohner, you can tell the vintage of a harmonica by the details of the trademark. The partial coat sleeves with shirt cuffs means it was made after 1924, and the engraved six-pointed star was used until 1937 when the Nazis ordered it removed from the trademark. Bought by my grandfather in the early 1930s. Comes with the original box which shows its 80+ year age, bu...t the harmonica itself is in good playable shape.
