If pops doesn't have one, keep watching gunbroker and auction arms. New stuff appears all the time. Given the price of the stock versus the gun versus parts, you might also consider buying another one, using the stock from it, and selling the rest of the second one as parts (probably will net a cheaper stock that way, if more hassle.) I'm assuming there's some sentimental attachment? I hope so, because it sounds like you're in for a hunt.
