Museum Archive: Vintage Marathon (with sonic blades), 3/5oz Nickel / Orange fishing spoon #8366

Bright orange enamel covers exactly half of the 2 3/4" (7cm) nickel spoon, creating a high-contrast finish designed for visibility. This 8366 model is equipped with two teardrop-shaped mini-blades attached near the tail, intended to mask the treble hook and provide secondary points of light reflection. Each sonic blade is stamped with the Marathon brand name and the size number 2, distinguishing this as a product of the Wisconsin-based company that operated from 1929 to 1979. Weighing 3/5oz (17g), the lure's construction features a heavy-gauge metal body and robust split rings typical of mid-century USA manufacturing. The specimen sits at a 4/5 condition rating, showing minor paint loss along the central seam and light surface wear on the nickel plating. Small areas of oxidation are visible on the treble hook shank and the attachment points of the auxiliary blades.
