Master Lock K7 Duplicate Cut Key for W7 Cylinders

My Shotgun trigger lock has been on there for over 15 years. Why? Because I dropped the key into the Atlantic Ocean alone with all my other keys approximately 20 miles offshore. Never bothered to get another key for the gun and forgot about it. Well about a month ago cleaned out the cabinet and saw the Ithaca shotgun decided to see if I could get another key from Master lock. Yup they had one. Sent it out. Works like a charm. Oh yea, gun works also.
