Museum Archive: Vintage Mepps Thunder Bug, 3/32oz Gold spinning lure #12557

Weighing in at 3/32oz (2.8g), this light spinner features a distinctively shaped gold blade stamped with a detailed wing-like vein pattern and the "USA" origin mark. Identified by product code 12557, the Mepps Thunder Bug is built on a 2" (5cm) frame with a segmented brass body designed to imitate a larval insect. This specimen is in 5/5 condition, showing an exceptionally clean gold finish across both the body and the notched blade. The treble hook is tied with a dense collar of brown and black feathered hackle, providing a natural contrast to the metallic shine of the hardware. The blade clearly displays the "Mepps 0 Thunder Bug" engraving, indicating its size and series within the legendary manufacturer's lineup. Every component, from the wire form to the clevis, remains straight and bright, highlighting its status as an unused addition to a vintage collection.
