GREETINGS, SimonP! The Lawman revolvers are J fame Colts, which were made to replace the Official Police Line and came out, I think, in '69. You usually see them with a 4" barrel and they came blue or nickel. Colt did switch barrels after a point, on the 2"ers. Originally, the Lawman had a bull-sort of stubby tube with no cylinder rod shroud. The later ones had the detective special barrel with a shroud. Both are .357's. Here where the hoot owls love the coyotes, you'll see them tagged for +/- $400. More for the 2" and more for nickel. As a peculiar happenstance, I noticed the San Francisco Model Club, whatever that is, had a 2" Colt Lawman for sale once upon a time. I saw one on e-bay. This was a miniature gun - about 2" long? Would look great in your display case, though, eh? Their model was the original, plain barrel. For what it's worth, the J Colt Troopers are adjustable sight .357's, the Lawman and Metropolitan were bare-bones cop guns with fixed sights, in .357 and .38, respectively. The J's aren't very well noted for smooth but they are accurate. I have seen a few examples with wondeful triggers, too, but these seem to be the exceptions more than the rules. Any J Colt ought to be a very sturdy, accurate, dependable piece that'll never go out of time. That's what they were made for.
