I purchased this Airweight S&W as my primary carry weapon and I honestly have no idea what model it is. The gun was refinished using one of Brownells' bake on teflon sprays when I purchased it, so some of the markings are hard to see. It is marked "SMITH & WESSON" on the left side of the barrel and "AIRWEIGHT 38 SPL. CTG." on the right. On the right side of the frame it has "MADE IN THE U.S.A. MARCAS REGISTRADAS SMITH & WESSON SPRINGFIELD, MASS" I tried using a white crayon to fill in the marking so they would show better in the pictures, but like I said, the markings had been mostly filled in by the bake on finish. The serial number is 104,xxx. Any info about what model, age, etc would be appreciated. I have never posted pictures here, so I hope I get it right.
