There's no reason to tear that rifle down, if you're not seeing any problems. To the best of my knowledge, my great-grandfather's model 94 has only been taken apart once, and it still works every hunting season. I may cringe at the "neglect" that this old rifle sees, but it's hard to argue about it when the darn thing just keeps working every time my dad takes it out of the closet. Reliability is one of the great things about classic lever guns, IMHO.
