I have a vintage 1980s " Fishing Lures" magazine ( from the Bassin')with an article that talks about it. Story was Ed Chambers, when Zoom was a small company, Made a batch of Amber that came out wrong for some reason, it was cloudy. At some point he had a tackle store ask him if he had anything "different", so he pawned of the mistake batch. A couple anglers won. Couple tourneys, and it got mentioned, creating a craze at the time, eventully making Zoom a national company. Pumpkin was the color, seed is the black flake. Not sure if it's true, but the article was done in conjunction with Ed Chambers, wih pics of the operation.
