I would have guessed $750 because I almost bought one from a friend two years ago, but what do I know? I was going to buy it just for the wood that was on it. I didn't need an 11-pound shotgun to go with my 12-pound waders.
Looking at the 22nd Ed. of Fjestad's Blue Book, the cheapest one, in 100% condition, is the one with the wood stock. Camo or synthetic is more.
MSRP = $1265, 100% = $950, 90% = $650.
Maybe if you could get them to throw in a nice case and some ammo...
