Doesn't surprise me a bit.
Happens to me all the time, although not necessarily with the exact same model. But one great find immediately following another is common in my experience (especially when I am down on funds from the first buy 
). But then, of course, you can go weeks or even months finding nothing interesting at all. 
Oh, I saw the post and lusted badly after both of them.
I did score a new-but-no-box Model 3954 from another member, but that and two other purchases have left me dead broke until I sell something. 
Doesn't surprise me a bit.
Well wait until you see what old Mbliss57 has to show for 2-fers now! I just bought a LNIB all correct pre 39 from our good Forum and SWCA friend Model3SW. Then within days after I found another equally as nice and also all correct in a FTF deal. Of course I bought both. Well techinically I will buy it this afternon...so never a done deal until it's in my safe. But talk about rare.. A pre 39 in the original box with original paperwork... What are the odds? And yes I will show them off.. Too nice not to display...
Amazing.
Some folks have all the best luck! And, let's not forget, the free cash necessary to buy that awesome luck! Can't wait to see them! 
I will show the trio. Hard to believe anthing that is 63 years old can be in that kind of condition. But they are. The 2 will bracket your serial number. One in the 1800s and the other very low 2300s. "When preparation meets opportunity"... I like that!Yes it does Brad..
As far as finding doubles.. it does help a lot if you happen to have the funds available when opportunity knocks. That is the definition luck .."when preparation meets opportunity".
Mind if I borrow it from time to time? 
I am certainly guilty of it, but I have always attributed it to: a) The purported lack of spare parts for S&W semi-autos, and, b) Massachusetts (where our selection of vintage/all-metal S&W semi-autos seems to be much more limited than in other states). But probably the better answers are: a) Because they're relatively inexpensive (in the context of the broader gun collecting realm) and, b) Because we can.
Exactly what I'm talking about Bam.
We just keep buying and buying even when we already own one... or two... or three. What does that say about us? I'm sure some revolver folks do the same thing, but it appears to me to be mostly a semi-auto affliction. And is there a cure for it? Or do we just have to keep buying more safes and try to live with it? Lack of sufficient on-the-spot knowledge has bit me in the behind many times... and Lord knows that he who hesitates (to do some price or model research) is lost.
No one to blame but myself in those instances. 
Yep. That's what I tell myself... and the good wife.
"But Sweetie Pie, this one is nicer than the one(s) I've already got." It's all about being convincing... like you really believe it! No, no, no Bam.
I'm talking identical duplicates, triplicates and so on. In my senile old mind, revolvers with different butts, different finishes and/or different barrel lengths are not to be considered identical guns even if they start with the same model number. 
You're making my point Bam.
One would think that with the wide variety of 3rd Gens available, a serious/diligent collector could keep going for a very long time and never buy the same gun twice... ... but no, we buy duplicates of the most desirable ones (in each of our own personal opinions)... and yes, in large part due to the relatively low cost for the value received. I fell in love with the first Model 3953 that I ever came across. The trigger was outstanding on it. Impressed the heck out of me. Must have been worked or something... who knows? Unfortunately, the frame was cosmetically damaged and that was a deal killer for me even given its low price.
Nonetheless, I wouldn't give them up for anything. I like slender and nothing beats a DAO 3rd Gen compact unless maybe its a DAO Chief's Special.
