You might get a jump on things buy going out and buying some of the following things if you don't already have them.
Sandpaper: I like the red Garnet type for wood. It seems to last better than the flint/aluminum oxide types. Get several sheets of 80, 120 and 220 grit.
For metal, buy the Black Silicone Carbide wet/dry paper. I suggest several sheets of 220 grit. Some 320 and 400 grit paper is good to have. You probably won't need more than one sheet of 400 grit.
File: A new 10 inch flat MILL file will be handy.
A hobby knife with a large handle is handy. I use an Exacto which takes #2 pointed blades. This is handy for making tiny cuts that may be required to get the lock etc to fit in the mortice.
Be thinking about the metal finish you will want.
Some folks use Instant Blueing, some use browing, some "age" their barrel so it looks 100 years old.
There are many options so before buying something to finish the barrel give it some thought.
I believe your gun will have a Walnut stock. If it does, you probably don't need any stains. You can decide that issue after you get your gun.
