Nah, they've been using it in Nebraska for a few years now.

Even most of us old "Boomers" finally figured that one out.
Now, with regards to the reel yellowing, it looks to me like someone decided to try a little clear-coat with lacquer. If it were mine, I'd remove the handle and wipe it with a lacquer thinner rag. If it's lacquer it will come right off with no harm to the metal. Keep it away from any plastic, though. Acetone might do it, too, but it will take a lot longer. Then I'd proceed accordingly on the rest of the reel.
