grey2393: The 3rd Edition notes that the .38 spur trigger 2nd Models were made between 1877 and 1891, with a serial number range of 1 to 108,255. Your .38 seems to be toward the later part of the run, probably in 1887-1888, would be my guess. I would letter it; S&W will have the date of manufacture. The 3rd Edition also says the pistol should be $325 for "Fine" and $500 for "Excellent, as mmaher94087 noted. I picked up a pair of these that lettered to 1885. Neat little guns, and you don't see a lot of them.
