Hi,
I like the responses. If I happened upon this, I would keep it.
I would never be one paying 2k, 3k +...
The colt action (vintage) is clockwork, and few now know how to repair and tweak it. I'm not sure if the modern cnc /mim colt plants could service it.
They are collectable. Not as robust as a 586/L frame or service /speed six /gp100 etc.
We don't know how much you paid. We don't know what you are into. We don't know if you're single or married, hard up or flush with cash, have kids or childless etc. All of these qualifiers might change our answer.
If you have a kid into guns /shooting / self defense / collecting this would be a princely gift on their 21st etc.
If grand pappy left it to you but you sure hated that jerk, or it invokes "meh" from you and you want that glock because self defense starts at 15 rounds on tap... Why not move it along?
As mentioned they've already maxed out in value. Covid madness hasn't made them worth 10k.
You could probably still sell it and buy a beater car with the money.
In my present day financial situation and armory, if I looked in the safe and said "honey, when did we get this old python? Must've been a wild night..."
Then I would keep it. I would take good care of it, but also use and shoot (though not carry) it. And I'm raising kids to love and appreciate the 2nd amendment and the shooting sports.
So when of age, they could have a gladiatorial battle royale to inherit that sweet blued slick colt goodness.
For revolvers.. That vintage python action is nice and they'll never be made quite like this, in that finish, again. To me that makes it special. Not at present asking prices, but if I suddenly possessed what you posted.
As said, even the packaging and paperwork matters. Check out gunbroker.
