The steel bells I have looked at closely have had very little if any swelling inside at the bottom, where you would expect a sound-bow. Again, it is the profile rather than the metal which gives most steel bells such awful partial tones, with wildly sharp hums. James Harrison achieved a similar effect - very light bells for their note - with bell metal. Harrison did it by making the bells extremely short-waisted compared to the= ir diameter, though.
