Museum Archive: Vintage ​Marathon (with sonic blades), 2/5oz Red / Nickel fishing spoon #13551

Adorned with a vibrant red enamel top, this 2/5 oz (12 g) spoon showcases a distinctive pattern of blue spots encircled by white halos. Two slender nickel sonic blades are mounted near the rear via split rings, functioning to reflect light and break up the silhouette of the bronze-finished treble hook. Produced by the Marathon Bait Company—a Wisconsin powerhouse from 1929 to 1979—the lure measures 2 1/4" (6 cm) and features a polished nickel reverse side with a clean finish. The specimen is cataloged under product code 13551 and presents in 5/5 condition, maintaining its original luster and sharp paint boundaries. These specialized sonic blades were a hallmark of Marathon's mid-century innovation, intended for casting and trolling in various environments.
