Possible new acquisition

[Arogue]

I have had good luck recently while out searching for watches. Friday I found a ref.5513, Saturday I found a ref.1603. But today, today I found what is below. A ref 16013 from 1984. Comes with authentic box (although not original) with Rolex matchbook still intact. If all checks out when I go back to look at the movement this will likely be mine.
