Frank,
No photos. This info is from the 4th Edition of the Standard Catalog of Smith and Wesson regarding the Model 38: Bodyguard Airweight. The revolver was introduced in 1955 and produced through 1999 although some may have shipped after the end date. It was later produced as the Model 438 and later still as the 638 with stainless steel cylinder and barrel. The Model 38 is chambered in .38 S&W Special, has a five shot fluted steel cylinder, alloy frame with 2" steel barrel. Early model barrels were pinned until 1982. The Bodyguard was unique in that the airweight version came before the steel framed version (Model 49 Bodyguard). The Catalog has a picture of a Model 38 that belonged to Clyde Tolson, J. Edgar Hoover's second in command and lifelong companion. The Bodyguard Airweight came in blue or nickel, with some report of nickel cylinders in blued guns. I have a nickel Bodyguard from 1988 that's one of my favorite carry guns. The Catalog lists the values as $550 Excellent, $475 Very Good, $325 Good. But those are only guidelines and estimates. I think I gave $400 for mine and it's at least very good, but no box/papers, etc.
PS. It's always okay to ask questions on this forum. You will usually get good answers. Just ignore cranky posts. If you go the S&W Forum and search Model 38, you'll get lots of information on the revolver.
