First off when metal is left 'in the white' how does one keep it from rusting if you choose to leave it in the white? Something tells me just oiling it will not do. Secondly, how was the metal typically finished on the typical 'working mans muzzleloader' of say the late 1800's? Did the builders brown the metal or just leave it in an un-browned or un-blued state and left it to patina over time? Go easy on me ok! Not looking for my little project to be perfectly PC, just need pointed in the right direction. Thanks.
