Thank you all for the kind comments.
Rick,
I've actually have shot it before I finally finished it. Had to use it as my back-up gun in several matches when my other flintlock took a spill and cracked at the wrist. It's a little barrel-heavy, but its accurate.
Rich,
It likes your flints!
Satwel,
The barrel is a very dark brown, darker than results I have had in the past.
I used vinegar to neutralize and was still getting rust. I then did multiple vinegar treatments and applied motor oil to the warmed barrel and haven't anymore rust.
The lock I left as is--no browning, bluing, or gray finish.
Just 15 years of waiting-to-get-done patina.
