Welcome Doskias;
There are many interesting historical artifacts about the Post Office and postage. Thank you for the interesting link!
Be aware that even though the 12 Stat 705 has not been altered, moved or repealed and is still in effect today, you're gonna have a battle on your hands if you pursue it. https://postalinspectors.uspis.gov/i...shortpaid.aspx
There won't always be a battle. I and others have had mail successfully delivered numerous times while utilizing the de jure postal rates.
There are some youtube videos on this topic too
