Museum Archive: Vintage Marathon (with sonic blades), 2/5oz Nickel / Light Blue fishing spoon #9790

Nickel-plating on the convex underside provides a high-contrast flash against the light blue scale finish on the front of this 2 1/4" (6 cm) spoon. Weighing in at 2/5 oz (12 g), the lure is equipped with a unique hardware setup featuring two small, elongated sonic blades attached to the rear split rings alongside the treble hook. These blades are designed to create visual flash and movement near the hook point, mimicking the tail of a baitfish while partially masking the hardware. Stamped clearly with the MARATHON name on its silver-toned back, this specimen originates from the Wisconsin-based manufacturer that operated from 1929 to 1979. The product code 9790 represents a classic American design intended for casting or trolling. The condition is 5/5, showing a very clean finish on both the scale pattern and the polished nickel surfaces. The teardrop profile tapers toward a single line-tie hole, balanced for a steady retrieve.
