A set of hands for a mid 60s' gilt 1016 won't come cheap and you may need to stand in line to get some.
I'm thinking 1016 hands are unique to that reference, the hour hand (probably) and the minute hand (possibly) being longer than that used on Submariners. And some data suggests the sweep hand has a longer mounting pin (like the 1680 / 1665 hand set perhaps ?). And if Rolex were still using the flat hands in 1967, your task gets more difficult. I'd guess about $2500 + now for a correct, goodcondition gilt 1016 hand set.
So Jon, you may have hands that are the wrong length, the wrong profile and the wrong metal. You may want to research more before closing the door on any option for compensation from the seller.
