"When French engineer Andre Meulnart invented the iconic Mepps spinner in 1938, I wonder if he knew what kind of revolution he would bring to the world of fishing. The Mepps (a French acronym for Precision Equipment for Sport Fishing), when combined with nylon line and the spinning rod/reel, changed fishing forever. When Wisconsin native Todd Sheldon discovered this killer lure in 1951, it changed his fortunes as well. Within five years, Mepps was a household name, and every company was struggling for a version to compete in this new market that Mepps dominated. You own a pair of Mepps knock-offs designed and sold by Heddon, and called Hep Spinners. The Hep was introduced in 1954 and sold reasonably well throughout the decade, but lacked real lasting power. Interestingly, although it is a close copy of the Mepps, I never had anywhere near the success fishing a Hep spinner as I have the original French version. They are worth around $5 each but you may have better luck than I have had fishing them. To see the introductory ad for the Hep spinner, click here."
