Museum Archive: Vintage Marathon (with sonic blades), 2/5oz Copper / Red fishing spoon #10275

Flashes of light reflecting off the red prismatic insert immediately draw the eye to this 10275 specimen. Weighing in at 2/5oz (12g), the spoon features a classic teardrop profile with a rich copper finish on the convex side. Attached near the tail via split rings are two elongated mini-blades—often referred to as sonic blades—which provide a secondary layer of visual attraction while helping to disguise the sharp treble hook. These small gold-toned accents are stamped with the brand's identifier, mirroring the clean "MARATHON" stamp found on the polished concave side of the main 2 1/4" (6cm) body. Originating from the Marathon Bait Company of Wisconsin, a powerhouse in the American tackle industry from 1929 to 1979, this piece demonstrates a mechanical approach to lure visibility. The Copper/Red color combination is well-preserved, and the overall hardware remains in excellent shape. This specific lure earns a condition rating of 5/5, looking nearly as crisp as the day it left the Wisconsin factory.
