As far as I can understand it, your argument has been that private individuals and groups were not allowed to own the WMD of their day.
The United States Statutes at Large, which I cited above, is the law as passed by Congress, and it specifically says that those rights and privileges of private corps and individuals were preserved, but they were subject to being called up at any time as the regular militia.
I don't know you from Jack, and all I am doing is reading verbatim an official publication of the State of Michigan.
I can scan it in if you like.
No, I have never claimed that the fedgov made illegal possession of artillary just that it was not what was referred to in the 2d amendment. And that militia artillary companies were not based on the idea that anyone could effectively use such weapons. Their officers had to pass a special examination (principally mathematics) to receive a commission as an officer.
