“A MANUAL OF PARLIAMENTARY PRACTICE: for the Use of the Senate of the United States.BY THOMAS JEFFERSON.” consists almost entirely of only references to precedents from Parliament.
The procedures of Parliament were used by our Founders not just because they were familiar with them but because they have true merit. They’re followed by just about every bicameral legisature in the world!
A pertinent difference in our legislature is that we did not maintain the British requirement that revenue bills not be amended by the upper House.
Blackstone/Tucker: “The exclusive privileges of the house of commons, and of our house of representatives, with some small variation are the same. The first relative to money bills, in which no amendment is permitted to be made by the house of lords, is modified by our constitution so as to give the senate a concurrent right in every respect, except in the power of originating them; and this upon very proper principles; the senators not being distinguished from their fellow citizens by any exclusive privileges, and being in fact the representatives of the people, though chosen in a different manner from the, members of the other house; no good reason could be assigned why they should not have a voice on the several parts of a revenue bill, as well as on the whole taken together.”

A priceless source for understanding the Constitution. It is best read not for seeking to make a point but for seeking understanding.
No one argues that the operations of our legislatures does not follow general Parliamentary Procedures.
You still offer no evidence or documentation backing your claim that the Founders circumvented the Constitution by “practice” enabling the Senate to originate revenue Bills via “substitution”.
Unless I see more than your opinion or supposition, this is the last I will discuss this subject, my FRiend.
