Hi there, I don't actually fish but I have a question about something that I think the board can help me with. I recently purchased a No. 100 Danielson Fly-Tying kit that looks like it's from the 1940's or so and I want to sell it on eBay. It has a package marked "Polar Bear Hair" (I'm not really sure if that's what it actually is) and my question is, does anyone know if it's legal for me to sell it, especially because I'm not sure that it really IS Polar Bear hair? Thanks in advance for your help!
