I think we're talking about different, but related, things here. "Broaching" as you've described seems a structural process. What I was originally asking about was the visible evidence of the barrels having been broached; the marks on the breeech faces.
The process I learned about to apply these marks is done by using 440 grit to polish in direction, and then 400 grit polish in a different direction with a very thin backer to create the breech face "striping" effect. Faux broaching?
I trust the historical account that all Parker barrels were broached. Thank you for sharing that history. If that process created the markings in the picture that Bryan provided, then restoring the marks wouldn't be wrong to do as I finish up refinishing these barrels.
Here's another example from Mr. Dudley's site:
