Your Coke machine is what is called a slider, it was probably made by Ideal. Mine is a Ideal 55. It is called a slider because you put the money in then slid the bottles over to the left and pulled them out of the machine. These machines were used all over the place, many out front of service stations. They had a compressor in the bottom that ran a refrigiration unit that kept the bottles cold, no cold water.
Almost every guy who grew up during the time of their use will tell you the story of how they pried the cap off a bottle while it was still in the box, then sucked the soda out through a straw.
