First of all, please forgive the bad photos. It's dark and rainy here today and I don't have the nice, natural light I usually do. So I took the pictures in my kitchen.
Here's a handy guide for the fisherman. Handy in spite of it's size. Depending on how you measure this, it's about 14 inches wide. It was produced by Russian River Products in Belmont, California (where we used to live!) It's nowhere near the Russian River.
Here's how it works. Say you fancy a bit of paddlefish. Just point the dial to him and the type of lure, bait, hook size, habitat and whatnot are revealed to you in code. Check the reverse side of the wheel to decipher the code and you're on your way. It seems to be a pretty comprehensive guide. If I were a fly fisherman, I'd want one.
Plus, it's shaped like a fish! Ha!
