Before you dive into this defarb, I would heavily research the 1766 charleville musket history. Knowing more information is best, and ensuring that you’re relying on good information as to the person doing your defarb.
You mentioned passing the 1foot test, that’s a tall order to fill for a Miroku charleville..
Bianchi’s book offers some great detail into the features and variants of the 1766 Charleville.
Here is an example of an excellent defarb by Gutenberg one of the best I’ve ever seen ,not sure if he’s still in business.
These were navy arms parts on a restocked walnut stock. With some rifle shoppe hardware mixed in. The Miroku lock is a pretty decent copy, as is the barrel.
Notice the lock panels are much leaner, the finish is not dull, it’s a semi gloss varnish.
The front band has been slightly opened at the mouth, not as straight profiled.
The rammer is button shaped, correct for an early 1766/68.
Most importantly you’ll notice the buttstock is longer with deep flutes that are dished in.
This is your best 1ft test defarb in my opinion.
No discernible proof markings on the barrel are required too, there is no consistent pattern of visible proof marks on any Charleville barrel. You may find one or two with a C or M on the breech. So the barrel should be left plain.

Lastly the best person to do your defarb is the one that is most knowledgeable about the pattern gun, not the person willing to do the cheapest work. Do your research, document your findings and ask questions, defarb your musket based on your research. (For the 1ft test).
