Conversion. Jukebox plant. A skilled milling machine operator, this employee of an Eastern jukebox manufacturing concern has already been given war work to do. He's aiding in production of electrical control instruments whose basic design is similar to the control device on jukeboxes. When jukeboxes still on the assembly lines have been completed this firm will devote most of its space to war production. Rudolph Wurlitzer, North Tonawanda, New York
