So I picked up a wester w75 boot knife in amazing shape from a fella. After some talk turns out he has a w81, w84, and a couple fillet knives as well. I'm curious if any of you experts have any opinion on these or possible fair values. They are all in what I'd say very good condition and have sheaths. I'm not to experienced in old blades and do not want to over pay if I decide to jump on them.
