you have a VMC 56, or if you prefer a Vendolator 56. It
Vendo and Vendolator were two separate companies, but merged in thwe later 1950's ( 1956 I think)
Vendo also produced 56 bottle machines for coke, in roundtop and square top models. a Vendo 56 is used to describe a machine manufatured by Vendo.
Here is the details I found on a website.
In 1956, Vendorlator merged with its former rival, the Vendo Company of Kansas City, Missouri. Prior to the merger, Vendo worked almost exclusively with the Coca-Cola Company, so the combination of the two companies made them the primary supplier of vendors to the soft drink market. Within two years, the companies were completely consolidated and operating out of the Fresno location. In 1988 Vendo became a subsidiary of the Sanden Corporation of Japan. Vendo moved its headquarters to Dallas, Texas in 2005 and the name changed to SandenVendo America Inc. They still operate today as a manufacturer of vending machines, in addition to commercial freezers, and automotive air-conditioning systems.
