This is a vending machine key for a snack or drink machine.  The key number is 7.  It is used.  It is made by Taylor USA and it has a #137 on it as well.  This is for a barrel style lock.  I have many other keys and locks as well as parts from vending machines if you need a certain one, I may have it.  I do combine shipping on items sold.  Check out my other items.
