Museum Archive: Vintage Acme K.O. Wobbler, 1/2oz nickel/blue fishing spoon #21531

Polished nickel paired with a vibrant blue flash gives this 1/2oz (14g) casting spoon a classic, high-contrast look that stands out in varied light conditions. Stamped clearly on the reverse side with the model name, this 1 3/4" (4.5cm) American-made lure from Acme, identified by product code 21531, features the signature "Sonic flipper tail"—a small metal kicker attached to the rear split ring. This component is designed to generate specific acoustic signatures alongside its side-to-side motion. The hardware consists of a sturdy bronze treble hook and robust split rings, all appearing in 5/5 condition, representing an unused specimen. Its teardrop profile and concentrated weight are specifically balanced to facilitate long-distance casting into deeper holding water.
