A working machine with new thermostat. The Vendo 63 is one of Vendo’s top-selling square-top machines. These are among the first square-top machines introduced in 1959 with a new, more modern-looking design, along with the Vendo 90 and Vendo 126. This machine used a slanted shelf design to vend, and could bend bottles of up to 12oz and even longnecks. They also used a Coinco electric coin mechansim, which allowed you to set it up to any price and receive change. They were made from 1959 until 1966 and were perfect for small stores due to their reduced size.
