Help identify 1950’s Coca Cola Vendo

Hi there!
I’m leaning towards purchasing this vendo but it will be the priciest piece I will be spending for an item so naturally I’m very cautious. I will clean it up while I use it in my office. The seller says it works so I will try it out with a bottle if I get it. I can’t read the label well and don’t see many that is all white. Any history on this make? What’s a decent price if it works? If it doesn’t? Thanks in advance!
