__"This is one of the most fascinating, overly-complex fishing devices I can remember seeing. Patented in 1952 by Mark Moore of Davenport, Neb., it is indeed a complicated scent system designed to "intermittently supply liquid lure to the water in the region of the fishhook." The goal was to attach the thin tube to the fishing lure or hook and every so often, press the syringe which shot liquid lure scent through the long tube and out the end, theoretically attracting fish. The great drawback, of course, is that the amount of tubing needed for actual fishing conditions greatly exceeded the length of the actual tube. Unless you were fishing directly below the boat, this was a massive design flaw. The Del Shure Lure clearly did not connect with the fishing public (the price was equivalent to $60 in today's terms), which is why yours is the first I've ever seen in the box. I'd value it at $30-$40. To see a picture of the patent for device, click here."
