Because it is difficult to keep track of who purchased the firearm from where the gun was shipped, most do not include that info.

Would a notarized statement on when purchased, where purchased, and who purchased (including serial number) help? Yes
If someone offered a 1873 undocumented Colt and said it was from Wyatt Earp, would you believe it?
If someone offered a 1873 documented Colt and said it was from Wyatt Earp, how much more are you willing to pay?
Who knows, maybe we will become famous and the firearms we currently own could be as sought after as Wyatt's 1873.
