I am a collector of the S & W 39 series. I have all the options for the 39's, 39-2's, 439's, 539's and 639, They come in blue, nickel, alloy, steel and stainless. Here is my favorite which is an engraved pre-model 39. Note the serial number and no model number. This is new in the box and I'd bet there aren't many of these still out there.
