Insert from Allcock's 1930 catalog.
"The "Sea Dazzle." This is a metal bait with coloured fins. Tests have proven that it will catch far more mackerel than any other spinning bait...comes in one size only 1-1/2 inch, 1/3 each. A splendid lure..."
The fins have discoloured, apart from this cosmetic detail it's in good condition, some rusting on the hook however still sturdy and all parts intact.
