Vintage K-B Bait K-B Spoon 4, 1 3/4oz copper fishing spoon #22312

Stamped clearly on the reverse side is the 'K-B SUPERIOR WIS. PATENTED 4' mark, denoting both the model name and its origin in Superior, Wisconsin. This heavy-duty copper lure, identified by product code 22312, weighs 1 3/4 oz (50g) and measures 4 1/2" (11.5cm) in length. The specimen is in excellent 5/5 condition, displaying a clean, polished metal surface that reflects the mid-century craftsmanship of the K-B Bait Co. Robust hardware completes the setup, including a brass barrel swivel at the head and a large silver treble hook at the tail. Known historically since its 1929 introduction as a tool for big fish, the design features a wide, teardrop profile with a distinctive pinched waist near the upper attachment point.
