Up for your consideration is a mid 1930's coin operated candy machine.
This machine was made by National in St. Louis, MO. They made a variety of coin operated candy, and cigarette machines. This model is the smaller version which vends 6 selections of product at 20 per column (120) total capacity.
Machine is complete with all (120) product shelves and vends fairly well on (5 cents) nickels only.
Coins will reject mainly just newer ones which there really isn't much you can do but remove it from the coins you are using to reduce the frequency.
A great pre war piece these were only made for a few years as production stopped for the war.
