Without running the current numbers, my guess is that you will probably find like guns on the net going for about $3250. Figure net prices are typically on the high side of the sale price by 10%, and you arrive at something around the $3000 mark like 8bore suggested.
21s are "supposed" to be upper crust, ST/BT/PG guns. If a particular example strays too far from that norm, it's hard to get people's attention. Think shooters vs. show pieces. If the seller has some sense about him, he will quickly come to that conclusion.
As to the wood, it only has value if you really want new wood. Otherwise you're just paying him to take an orphan project off his hands. To my mind there's not a lot of difference between semi-inletted wood and a raw blank. He can throw in the wood or sell it separately.
They look like nice guns.
