Welcome, Now Moving Along . . .
Greetings Chris43,
I see you're a new SWF member so allow me to be among the first to welcome you.
Okey dokey: Your 639 (I saw its images elsewhere in the SWF) looks nice, indeed. Let me also be among the first to congratulate you on buying a solid pistol that should provide many years to come of solid performance if kept well, starting with the recent recall.
The following information is provided by the Standard Catalog of Smith & Wesson, 3rd Edition, and whose authors, Richard Nahas and Jim Supica, regularly hang in these parts. Seriously valuable information, stuff you might think will never, ever apply to you, is available within. It is worth every penny of the money spent. Furthermore, because a No. 4 is in the works, you might well be able to get an absurd discount for Nos. 1, 2 and 3; each having important, relevant information on each handgun S&W has produced. Get 'em and you won't regret such.
Your S&W Model 639, Serial No. 830874, was produced in 1983. Narrowing it down still further isn't possible beyond a guess, which would place your gun as possibly made in the months of May through July. Should you wish to determine an exact date, it's available through S&W's resident historian, Mr. Roy Jinks for a price. Seeing as it's been some time since I've last sought deeper manufacturing information, I am unaware of current pricing, though it's been $50 in the recent past. It's worth every penny. Mr. Jinks works hard to establish Smith & Wesson pedigrees. It's doubtful you will find the money as having been ill spent.
The following pricing information is provided by The Blue Book of Gun Values, by S.P. Fjestad, Online Edition which, for $44.95 yearly, is the best buy, hands down, if nothing else but for the regular updating of market pricing. So valuable is this product to this collector, its sign-in page is among the windows opened when my browser is clicked upon for the first time each day.
Your Model No. 639, Serial No. 830874, and based on the pictures I've seen of it, is worth about $79.00. Your gun looks to be in pretty darn good shape, so it'll likely command top dollar. Otherwise, it may be worth as little as $ 15.75.
Um, oops? Sorry, wrong gun. (Just having a little fun, man.)
Let's see . . . Rated at 100-percent, we're talking $475 + $27 for a set of sights you don't have on your M639.
What is 100-percent? Everything sold with the gun still rums with it. The gun hasn't been fired since its purcahse and, when taken for an appraisal, must actually look like it's been respected and well treated.
The custom-added aspects of your pistol (nice ones at that) kinda upsets the apple cart insofar as long-distance valuation is concerned.
Inasmuch as I'm a collector and don't much delve into custom jobs (such generally being anathema to collectibles), the price of your 639 is questionable.
Sorry, Chris43, wish I could do better for you.
Nevertheless, welcome to the Forum. It's a great group of males and females.
Later.
Just aquired a like new 639 today, it has the round trigger guard with ambi safety and fixed sights. It has had a muzzle brake installed, but the original barrel bushing came with it. I would like to know the year it was made and a rough value of the pistol. The serial number is A830874. Thanks for any info.
