'Melody' was the first flipper machine manufactured by Bally. The rolldown version of this game is Bally's 1947 'Melody Roll'.
The playfield layout was used again on Bally's 1948 'Ballerina' but with a flipper-shaped stationary post in the center playfield in place of the triangular post.
Per Cash Box Feb-21-1948 page 36, Bally announced that shipments began that week.
