Thanks guys. I was thinking around the $500 to $550 mark would not be unreasonable. I called Lew Horton and they said it was not shipped to them, but oddly another 686 eactly 5 numbers away was. I called Smith and Wesson and they said it was manufactured in 1985, not in 1984 as the book contends a Lew Horton would be. As it does not have a white outline rear sight, I was thinking it was probably not a Lew Horton.
Sportsterguy I appreciate the heads up. I shoot my Smiths, and if it will not hold a decent group at 25 yards, I do not want it. I had a 2001 686-6 with the dreaded IL, and it would shoot excellent groups all day long. But alas, I could not get over that lock and traded it away.
