Don,
It may indeed be a 3rd Model (small frame) DA revolver. But, it is not a #3 size frame, not in .38 S&W cal.
You have asked about the price twice now. What is the price being asked? If you want more info, tell us more about the revolver!
(5 shot or 6 shot, barrel length, nickel or blue finish)
My best,
Blair
