Breck has done a great job on every barrel I have sent him. Mostly Parker hammer guns.
I have some great Parker examples, but here's a before and after Breck did on a 15 gauge percussion sxs with 34" barrels, likely made in the late 1850s. Most of the finish was gone and I wanted the barrels to be protected. This is a great shooter, probably the best muzzeloading shotgun I have shot in fact. It's just like shooting a normal cartridge gun once it's loaded...
This gun is now a treasured possession, that I just love. It will be joining me this fall on some hunts for sure
I think you will be happy when your barrels come back.
