Tom,
If it were me, I'd start at the CMP. Hopefully, you're within driving distance of the 2 CMP stores in Ohio or Alabama. Considering the condition of the stuff I saw in Port Clinton last summer, I wouldn't trust them with a mail order.
I agree with Torpedoman, that for me, the muzzle wear would be my first check to try and get a good shooter. Next, probably metal condition and stock condition in that order. You can usually clean, steam out the dents, and refinish the stocks to make them look a little better.
Try some gun shows and shops as well. Price will vary with condition and collector value, but the CMP prices should give you a baseline. Good luck.
Jim
