This is likely a 1930s Supertone mandolin made by Harmony. They made this style of mandolin for a long time, solid birch top, back, and sides and a poplar neck, but the tuners date it to the 1930s. Besides, Supertones only had a paper label inside that often goes missing, while Silvertones (the post-war versions) almost always have the name on the headstock. Sold!
