Mills Watson : Diamonds Are Forever?

He has no credit or even uncredited credit for Diamonds Are Forever but I wonder if he is the guy in the car behind Dr. Metz at the gas Station? Anyone know?

I was wondering about Tora Tora Tora which was filmed within a year or two of DAF. There is a scene showing the USS Arizona and one of her officers looks like Mills. There is somebody speaking into a loud speaker about "Manning your stations" on board Arizona that sounds like Mills
