With the brief description that you have supplied,I would say that you have a SMith and Wesson model of 1905 4th change revolver.
By your serial number and description it sounds to me that you have a .38 military& police Model of 1905 4th change.These smith and Wesson handguns were made between 1915-1942.The total production was 758,286 made. I would say that yours was produced between 1923-1925.for a fee you could contact smith and Wesson and they will research the handgun in question and issue a letter with their letterhead and history of your smith and Wesson.

We can't tell just from the serial number, and not all S&W revolvers HAD a model number. Earlier revolvers may have a name, such as the Outdoorsman, or a year, such as the 1905. You also want to be certain your revolver IS a Smith & Wesson- they owned the name to the .38 S&W CARTRIDGE, so a non- S&W revolver might still be marked with the caliber of .38 S&W, but be made by another company- there are likely several hundred thousand of these out there. If you revolver has a model number, open the cylinder, and look at the frame under the cylinder crane, it will be stamped there.
