I'm a big fan of TVM . . . my first build was their late lancaster kit . . . I'm only on my second now, with Jim Chambers, but I have nothing but good to say about TVM . . .
However, they should really do more shaping on the front lock panel . . . I did look at a pic of mine and there was a pencil guide line to follow, so no one is to blame but us rookies. . .
You have a great gun . . . TVM makes sure of this with their lock inletting, trigger inletting barrel and touch hole. . they do the work that makes sure it goes boom 3 times . . . but I agree that your rifle deserves work on that front panel. You've got the ability, as seen in your other posts, so whenever you get back to that, I think you'll be pleased with how much that changes the entire appearance of the rifle in that area.
I am not a pro, and I had the help of a coach that made all the difference, but I found that a round chain saw file worked best for me in shaping the lock panels. . . he had a few other methods, but for a novice like me, that was easiest.
