Thrifted (what I was told was) a cast iron teapot! Noticed while cleaning it has some weird bits to it, can anyone tell me if this is safe to use?

Pic 1+2: Weird spot of orange by the spout- is it normal to have two holes leading into the spout?

Pics 3+4: Black flaking material where the lid rests

Pics 5+6: Just some pics of the teapot itself
