A note about "Revolver Values" - especially Colt and S&W models that are still sought after today...
I'm in my mid 60's ...and I love the N frame S&W model revovlers ( 27's, 29's, etc ...especially the older versions like dash 2's in Nickel )...and while the Colt snake guns don't fit my hands as well I appreciate their style ( not the trigges so much )...but having said that, talking to a few buddies that own gunshops in my area ( a relatively affluent metropolitan area )..million dollar homes are not uncommon, fastest selling cars in area are Lexus, Porsche, Mercedez, BMW.../ there is a lot of "new money" high tech jobs etc in area...and they're spending a lot of money on toys and guns, but:
a. any gun over $ 800 is not a common sale to shooters under 40 yrs old..
b. revolvers - tend to sit in case a long time even if under $1,000 ....over $1,000 they sit even longer ...for shooters under 40...
c. Wilson Combat 1911's ( avg $ 3,500 starting price ) are not in inventory ....and shooters under 40 might appreciate them - but they aren't buying them. Same on Ed Brown, Les Baer 1911's...they tend to sit ...new or used ..priced $2,000 - $ 3,000 .....
My point is, while I love the older revolvers and will pay a premium for them - I have virtually everything I want ( about 25 S&W revolvers )...and while my boys in their 30's and 40's are happy to inherit them someday - and they enjoy shooting them - they aren't going to spend $2,000 on any gun ( based on what they tell me )....
and my grandkids ...( teenagers & up to 24 yrs old )...kind of like shooting the older guns ...but rather than shoot my 1911's in 9mm, or the S&W model 27's....when we go to the range they would rather I rent the "cool guns" in the rental case ...poly frame stuff they see in the movies, or on video games... and when they turn 21, that's what they look at buying the most.
So I don't know about the long term value of Pythons or S&W model 27's...the bubble might burst ...or it may level off.../ I don't know ....but I think the risk of losing value on these old revolvers is higher today than it was 10 yrs ago. ( so ask around / it might affect your decision ).
