My guess is you have a British threaded shell. I just check my old memory banks and you can drop a British threaded cup right through the bb shell on an Italian frame. It slides right in. It may be French but My bet would be on British. I have also seen screw ups were people have tapped frames the wrong way around take a look for any damage and good luck with it.
