Museum Archive: Mepps Thunder Bug, 1/8oz Gold spinning lure #6778

A weight of 1/8 oz (4 g) makes this specific spinner an ideal choice for ultra-light tackle enthusiasts targeting trout or panfish. Adorned with a Gold May Fly pattern, the blade features intricate veining meant to replicate the wings of a natural insect, aligning with the Mepps goal to 'Match the Hatch.' Measuring 2 1/4" (5.5 cm) in length, the lure is built around a segmented brass body and a sharp treble hook, maintaining the classic construction associated with American-made tackle from Antigo, Wisconsin. This specimen is unused, preserved in its original blue and yellow blister pack. The manufacturer identifies this specific configuration under product code 6778, though the backing card further specifies it as a TB1 MYF-G. Unlike traditional round blades, this blade shape is designed to provide a specific flash profile that mimics the silhouette of a mayfly in the water column. The gold finish remains bright and clear, reflecting the high manufacturing standards maintained for decades.
