Museum Archive: Vintage Heddon Sonar 431, 1/4oz Gray fishing spoon #7699

Stamped clearly with 'SONAR 431' along its metallic blade, this vintage piece showcases the classic engineering Heddon brought to the lure world. The Gray finish features a detailed hexagonal scale pattern transitioning into a silver-toned belly with soft yellow and red accents around the gill area. Measuring 2" (5 cm) and weighing 1/4 oz (7.5 g), the metal body includes three distinct attachment points along the spine, which allow for manual adjustment of water resistance and retrieve depth. Carrying the product code 7699, this specimen is in 4/5 condition, with the original hardware showing some age-related darkening on the treble hooks. These hooks are positioned at the belly and tail to maximize strike potential during vertical jigging or steady retrieves. The forward-most adjustment hole is designed for high-speed presentations, while the rear holes are typically used to increase drag in deeper water columns.
