springfield arms trapdoor
My grandfather passed not too long ago after going through his things I found an U.S. Springfield arms trapdoor rifle model #1844 which was manufactured in 1891 I also found an Hopkins and Allen double action #6 pistol these guns were not taken care of very well the pistol has some outside rust and the rifle has some rust inside the barrel I would like to know if there is any way to clean these guns and if there is what is the best method I would appreciate any help with this
