Museum Archive: Vintage Marathon (with sonic blades), 3/5oz Gold / Green UV Glow in UV light, Fluorescent fishing spoon #5668

Gold and fluorescent green UV glow paint divide the surface of this 3 3/4" (9.5 cm) metal spoon, creating a high-contrast visual meant to stand out in varying light conditions. Two slender, silver-colored willow blades are attached to the rear split rings, a specific design element intended to create light reflections similar to a forage fish's tail fin. This Marathon Bait Company piece, originating from a manufacturer that operated in Wisconsin from 1929 to 1979, showcases the brand's unique "sonic blade" hardware configuration. The interior concave side of the 3/5oz (17g) lure displays the manufacturer's mark stamped into the polished brass body. Identified by product code 5668, the specimen is rigged with a robust treble hook and rates a solid 5/5 in condition. The fluorescent finish is well-preserved, and the sonic blades retain their original metallic luster against the painted body.
