The Carousel gumball machine was started in the 1950’s by Arthur Gold. In the 1980’s the brand was purchased by Ford Gum & Machine. The machines are cast iron with glass globes. They are made in different sizes known as the King, Junior and Petite (like mine shown in the photo). They still make replicas today but the originals are sold on auction sites for a little more. You can also buy parts for all the models.
Mine has advertising on the glass that says “Specialty Atlanta” and has a picture of a coffee cup? The idea is that they are banks. On mine, if you remove the top screw you can load gumballs and the bottom releases to get your money!
