PimplySwede,
They were purchased well over a decade ago at Dorn's hardware in Madison. The neat thing about Dorn's and other smaller locally owned retailers is that they don't need a large quantity of any given product that would justify setting up a sku or upc like they do in the big box stores. Just like you eluded to, they can have stock of small start up companies or even hobbyists. I purchased these the initial year I started to fish on Lake Michigan and bought my downriggers.
Of any setup I run, almost invariably I will include this particular spoon in the mix. One was lost on a big fish that ran and ran and just as I was turning the boat to give chase, the line snapped. If I knew then how productive this lure would be for my particular boat speed, I would have purchased every one in the store.
Not sure if anybody has tried this tactic or not... but on our next outing I am going to attach some pork rind style trailers made by Fat Cow to various spoons and flies. Have played with them on the clear water of Rock Lake (Jefferson Co.) and they look like they would be somewhat enticing.
Back to the original lure topic, it is little gems like these that keep me dragging my wife to rummage sales and the like. There are certain types of lures and older rods with less graphite and more of a parabolic softness that are great for certain situations. My guess is that if I ever encounter these lures again, that may very well be where I find them.
Thanks for reading and commenting and good luck on the water.
