I picked up this Model 19-5 6" at a local "widow sale" today for $400. I think it is in very good condition, and the walnut stocks seem to have some better than average figuring to them. I'm very pleased with the purchase, and now just trying to determine an approximate date of manufacture/shipping (there was no box) and approximate value. Based on the serial number ACY5651, can someone tell me when this pistol was made? Comparing it to some of my other S&W serial numbers, I'm guessing somewhere between the late 80's and early 90's, but could be way off. Also, I think I got a pretty good deal on this gun; but would love to hear estimates of fair market value. Thanks!
