Condition wise I think it looks good.
I got an Albini Brandaelin that looked like a piece of rusty tubing stuck to a lump of wood! It cleaned up enough to make it good enough to be a wallhanger, but it had had a hard life. The forend was split and the front barrel band is missing and the backsight sight has been ripped off.

If you want to clean the bore get a length of aluminium tubing and cut a slot in the end, about 1/4" in, so you can put a strip of emery cloth in and wrap it around so it fits the bore. At the other end rivet a piece of aluminium or brass bar in so it will fit in a drill chuck.
All you have to do is keep going up and down with the drill running and change the emery cloth as it wears. The barrel will come up looking reasonable eventually.

If you cannot fix the crack in the stock with epoxy resin and the piece can be detached from the wood, knock a couple of panel pins in part way and snip the heads off. Then press to two halves together. This will mark where the pins are and then you pull out the panel pins and drill holes where the marks are and you can epoxy a piece of dowel in. If you do that put a slot in the side of the dowel so it wont air-lock.
