I saw exactly that at the fun show last weekend. Almost bought it too, instead I picked up a beat up S&W model 13.
The table was Larry's Guns and Antiques. Day number is 225.235.9339. IIRC he was asking 275 for it at the show. He will might have it at the show in Gonzales this weekend, if you want it I would call.
like I said I only paid 225 for a smith, the grips need to be replaced and their is a bit if surface rust but the cheapest one I could find on GB was 325. Larry said he gets these guns from the police evidence locker when they dispose of them and he does a pretty brisk business in used guns at the shows. He also had a couple of Colts in great shape but they were both 38's and were out of my price range.
