I don't have an answer for you, but that old stuff is really cool, isn't it? I have a couple of really old, unique jigs with spinner blades incorporated. My favorite old thing that I found in my dead uncle's tackle box is a glass tube filled with liquid (formaldehyde?) and a rolled up piece of catgut. It's probably of no value, but it is cool, and the lable is still perfectly readable. Enjoy!
