Museum Archive: Vintage Mepps Thunder Bug, 1/8oz Brown spinning lure #6530

Segmented like an aquatic larva, the tiered body of this spinner is finished in a deep bronze-brown. This Mepps Thunder Bug, identified by Product Code 6530, weighs 1/8 oz (4g) and measures 2 1/4" (5.5cm) from eyelet to hook bend. Its most distinctive feature is the wing-shaped blade, which displays an intricate yellow vein pattern over a dark background to mimic a natural insect. To further the bug-like profile, the manufacturer added a dressed treble hook featuring tan feathers and subtle flash. This specific American-made specimen maintains an exceptional appearance, earning a condition rating of 5/5. Collectors often look for these specialized Mepps models because of how they deviate from the standard Aglia blade shape to provide a more entomological silhouette. The wire shaft is securely twisted at the line tie, typical of the durable construction seen in mid-century Mepps production.
