If you have any intention of building a representative Bucks County gun you need to study some originals or, at least photos of originals before starting that kit. The kit buttplate is incorrect and doesn't even match the one on the finished gun in TOW's catalog. And, as Fred pointed out, the gun shown is not anywhere close to a Verner. The buttplate is the wrong style, the entry pipe is not correct, the end cap is too long,the ramrod pipes are too short, and the carving is totally wrong. The side-opening patchbox, which is a signature Bucks feature, is missing in your video. It would be a shame not to include it if you are intending to make a Bucks gun.
There are two known, signed examples of Andrew Verner's work. Both are very similar and elegantly made. A copy of a Verner gun is not for the inexperienced builder. Study the work of the original Bucks makers like John Shuler, George Weicker, and Jacob Daub and try to get as close to the "school" as you can. The result will be much more satisfying.
