If it's not level sometimes it'll jam up or a nickel will get hung up. It's extremely old and just overall beautiful piece of history. You can mount it on the wall or on a Coca-Cola stand. I've seen both done.
Last picture under Thomas flooring for serious questions. Lock has been removed and not on there. It will need a new lock and those are found just about anywhere. Especially ace hardware if you have one near by in your state. This item is in the category "Collectibles\Banks, Registers & Vending\Vending Machines\Soda".
