I'm searching for a gold expansion band with rectangular onyx inserts for my late stepfather's 1962 Sea King. One of the onyx inserts fell out on mine. The gold borders surrounding the inserts are smooth and without markings - I've seen later bands that have grooved surrounds. If the onyx inserts are the same in both models, I'd take that later band and harvest the insert.
Hoping someone here has one, it's very sentimental to me.
