With these cast iron machines you can almost always assume they clean up to a working condition. Parts are all metal, very durable, and if anything is missing it's usually bobbin case, cover, shuttle or something like that. Any missing part are usually obvious, they can usually be tracked down (it's generally a question of patience and price), a complete machine is always a pluss. The worst of wrecks can usually be brought back to life, even if it take a lot of effort to get them looking good again.
As for the cleaning of the race and shuttle, there's usually enough room to clean thoroughly when the bobbin case is out. There is access partly from above and the rest you reach from under the base. I tend to use loads of cotton buds, tooth picks and those velvety microfiber cloths.
Good luck with the machine :- )
