Museum Archive: Vintage Marathon (with sonic blades), 2/5oz fishing spoon #5640

A teal painted finish accented by a prismatic diamond insert defines the visual profile of this vintage spoon from the Marathon Bait Company. Two elongated, silver mini-blades are attached to the rear split ring alongside the treble hook, designed to provide extra flash and visual interest during the retrieve. This specimen, assigned product code 5640, measures 2 1/4" (6 cm) and weighs 2/5 oz (12 g). Flipping the lure over reveals a clean, polished metal surface featuring the classic MARATHON manufacturer stamp, a hallmark of the Wisconsin-based company that operated from 1929 to 1979. The paint and reflective decal remain in exceptional condition, earning a 5/5 rating for its preservation. The hardware and sonic blades show no signs of corrosion, making it a well-kept example of mid-century American tackle manufacturing.
