This Schermack two-unit machine with Models 45 and 310 features two separate stamp dispensers mounted to a single metal base with perforated front tray. Each dispenser has a metal face with crank handle. The interior metal mechanisms are covered by clear plastic canopies. One key services the front lock on both devices.
Joseph Schermack is generally credited with producing the first practical stamp vending machine. In 1910 he introduced a “profit-sharing” model where he sold two two-cent stamps or four one-cent stamps for a nickel, and in 1926 he formed the Sanitary Postage Service Corporation.
