Drew, I am not wanting to offend you, just trying to help.
Blue book is tough to quote based on reality. I am a collector who really works to find a good deal on a gun. I see guns like yours quite often on fair market auctions and that is real world prices. If you check prices at big dealers you may see some priced very high but those are for the impatient buyer who has more money than time to find a real bargain. I dont think you have a chance of getting more than 1k for your gun unless you use it for trading material on a more expensive gun at one of those high priced dealers...Here are some current auctions, I know they are not exactly the same or same condition but if I watched for 6 months I would find one like yours for that price range
