Johnnys advise is good, maybe clean it, and store it in a good soft case, when you handle it, make sure you oil it again, whipe it down with a oily rag, or use cotton gloves to handle,
the salts in the sweat on your hands will ruin the original finish, on the older 1911,s.
just cleaning may improve the trigger on a pistol thats been stored a while, dried grease, dirt ect, can gum them up.
you can get a nice 1911 clone, and play with that all you like, without ruining your historic treasure.
