I believe this Silver King nut machine to be from the early to mid 1950's. My uncle bought several vending machines, like this one, and located them in businesses in Nashville, Indiana. After my father passed, I inherited this one.
I do not know whether it works or not. I will leave that to the next owner to investigate. Looks like it is in fairly good condition for its age.
