Welcome to the Forum! That's a very nice LH Model 24-3 .44 Special. There are lots of Lew Horton and .44 Spl. fans here on the Forum so you're in good company. The triple-alpha s/n of your revolver dates its manufacture to 1984, and it's part of the .44 Target Reintroduction by S&W that began in 1983 (per the "SCSW 5th Ed."). Yours looks to be a desirable 3" bbl. LH combat variation (Product Code 100787), and there were approx. 1,000 revolvers manufactured. These were originally shipped with a black leather holster. It appears to be in excellent condition, and with the original box (and holster?) I would think it would be valued at $1800-$2K, perhaps more to the right buyer.
