The Magnus Organ Model 1510 is a mini tabletop child's organ that was part of the Magnus Harmonica Corporation's line of products, which were introduced in the mid to late 1940s. The Magnus Organ Corporation was known for its unique molded-plastic reed comb, which made its organs more durable and cost-effective than those with metal reeds. The Model 1510 was likely designed for children and beginners, with a two-octave range and six major chords. The organ's case was made of plastic, and it was part of a range of models that included tabletop and free-standing versions with varying numbers of octaves and chords.
