This is a 58mm Companion (basically a Classic with smooth alox scales). It has an image of a Lockheed P-3 Orion aircraft which is used by the United States Navy.
As you can see the scissors have the adjustable screw pivot. Victorinox stopped using those in 1991 (they use rivets since then), so this knife is at least 25 years old!
