Museum Archive: Vintage Acme Kastmaster, 3/32oz copper fishing spoon #18637

Stamped clearly into the copper surface, the 'KASTMASTER ACME TACKLE CO.' branding identifies this classic slab lure. Measuring 1 1/4" (3 cm) and weighing 3/32 oz (2.5 g), the metal body displays a bright copper finish with high-polish side bevels. A 5/5 condition rating reflects its clean state, though a single minute green spot appears on the reverse side of the copper plate. Product code 18637 denotes a size frequently used for light-tackle applications, featuring the original dark-finished treble hook and sturdy split rings. Acme utilized a specific alloy for these USA-made spoons to ensure the weight-to-surface-area ratio provides stability when used as a jig or in deep water environments.
