I think if you look closer you will see that it's a model 547. Guys over at the Smith&Wesson forum really like them and you could probably sell it quite easy there. Prices seem to range between 5 and 7 hundred on the auction sites. Tried to sell my 4 inch version for $500 a year or so ago without any luck locally. All in where you sell it I guess. A dealer probably wouldn't offer you much. You'd do better selling it privately. Think they only made about 5,000 of them. Good Luck.
