Museum Archive: Vintage South Bend Super-Duper 503 UV, 1/8oz fishing spoon #12331

Glow-in-the-dark properties define the Super-Duper 503 UV, as seen in the vibrant reaction of its chartreuse and orange-red finish under ultraviolet light. Measuring 1 1/4" (3 cm) in length, this compact American-made lure from South Bend is built around a single piece of bent metal, a design choice that sets it apart from traditional spoons. The stamped "SUPER-DUPER" lettering is clearly visible on the side, highlighting the heritage of a model that bridges the gap between a spinner and a casting spoon. At a weight of 1/8 oz (4.3 g), it is ideally suited for light tackle applications targeting trout or panfish. The specimen is in excellent condition, rated 5/5, with its original finish remaining vibrant and the hardware—including the rear treble hook and top wire snap—showing no signs of use. This specific 503 model, under product code 12331, features the UV-reactive coating which provides high visibility in deeper or stained waters.
