What kind of BB is inside? Did you try Sheldon's improvised method? Vice (LBS or a neighbour with a well equipped garage)? The loose material could be a leftover from brazing or whatever, a lot of frames have something rattling inside..
square taper Italian threaded BB- I'll check out Sheldon method. Prior to me removing/ attempting to remove stuck parts there was no rattling from inside the frame, and nothing I removed has broken/ corroded as far as i can tell
