Derek, you may want to hold off on sandblasting any of the metal, at least until you meet up with some of the guys and they can give you some advice. For the metal, Frontier 45 pads and hoppes #9, or your favorite gun oil, can clean off a lot of that surface rust without damaging any metal or remaining finishes. Some of the Frontier pad wrapped around a bore brush can clean up the bores and chambers too. As Mills said if the barrel wall thickness is good you may end up with a nice shooter there. Best of luck.
