Museum Archive: Vintage Acme Kastmaster, 1oz copper fishing spoon #18206

Copper plating coats this substantial 2 3/4" (7cm) metal slab, giving it a warm, classic look that reflects light differently than standard chrome finishes. Weighing in at 1oz (28g), this Acme Kastmaster is engineered from a specific alloy known for maintaining balance during descent and retrieval. This particular lure, identified by product code 18206, features the iconic aerodynamic taper that has made the brand a tackle box staple since the mid-20th century. The hardware includes a sturdy split ring attached to a dark-finished treble hook, which remains sharp and free of corrosion. The surface is exceptionally well-preserved, earning a condition rating of 5/5, showing no signs of use on either side of the copper-finished body. Acme’s choice of metal in these original spoons is what separates them from lighter imitations; the density is calibrated to ensure it holds depth in heavy currents or during long-distance casting. The hole at the head of the lure is precisely drilled for a snap or direct line tie, maintaining the intended center of gravity. You can clearly see the distinctive chamfered edges of the metal, a design element intended to catch light from various angles without requiring complex holographic finishes.
