Does anyone on here have any knowledge of what these are going for these days? I have the opportunity to pick one of the up, new in the box (no rifle mounted in it yet) and was told to "make a reasonable offer". I honestly don't know what a reasonable offer would be considering that all of the asking prices I've seen are very unreasonable to me, try more money than the gun that would go in the stock. This is a single arm BM59 Reese walnut folding stock like I said never been out of the box. My internet searches mostly come back, "no match found" or are outdated enough to be of no help. Any insight would be helpful, thanks.
