So, I have an opportunity to get 2 new to me dubl ducks. I just want some help verifying authenticity, and get an idea of what I can expect to pay for them. I've been trying to research but the market is all over the place on this stuff and I'm not that well versed in straights yet. Any help would be wonderful. Obviously they need a little work, but I'm a bladesmith and do all kinds of custom work etc. and have tons of experience in that department. I just don't want to get taken.
