I picked this up from an individual and all I can tell about it is that it's a S&W K frame round butt .38 Special. I have other Smith Revolvers and generally, I find the model number by opening the cylinder but where the model number normally is, is the number 309 and below that, 4644...neither of which I believe to be model numbers. Serial Number is on the bottom of the butt. It is six digits, 214xxx.

Also, on the right side between the Smith Logo and the cylinder, are a row of 6 dings that aren't dinged in. They are dinged OUT...like braille bumps in a perfect row that get increasingly closer together from bottom to top. How could that happen? Gun seems to be in good working order. Nothing appears out of whack...just wondering what it is and what could cause a row of outward dings on the plate?
