Harmonics are multiples some at octave intervals ABOVE the fundamental.
What is the predicted fundamental for this bell? 

For comparison, a 64ft organ stop goes down to 16 Hz which is audible, although 13Hz is not.
I was present at a demonstration where a sound meter was switched on and read 100dB although nothing was audible not even as a felt vibration, I think that was 10Hz

  It may well not be tuned. According to Bill Hibbert, there is little point in tuning bells of this size as most of the harmonics are too low to be heard.
