Double Cola Drink Box

I really have no idea about this drink box. I kno it came out of a funeral home in WInnsboro, Tx. The funeral home was tore down 20 years ago at least. How long it had been there & how long they had it is unknown.It was moved to my husbands grandfathers shop & stored. My grandfather in law has now given it to me. It was plugged up in his shop & still worked. I have not plugged it up since bringing it to my house because it needs a new cord on it to be safe. The box itself is green in color. The top has a silver door which is where you would lift it up to get your drink out I think. The part where you put the coins in I do not think works. It has an opener on it for the pop off top bottles. It has a door on the side which I think would be where it would be refilled. The other side has a motor cover vent like plate on it. It does have a small amount of rust on it. I have not tried to clean it or anything.The only sign on it says Double Cola with the word drink wrote real small right above it. I am wondering if this was before Coca Cola times or a totaly different product.
