As you have found, Elisinore Springer’s Collectable book of Bells – page 100 has the most information. Donna Baker has written 2 books Collectable Bells – mostly pictures with some information. I’m not sure which book St. Peter’s bell is in.
If you watched any of the video concerning the selection of the new Pope, you will have seen the ringing of this bell after the announcement with the white smoke of the selection of a new Pope. This bell is a souvenir bell replica of the large bell in the Vatican and has the 12 Appostles on its skirt. The handle at top is the Papal Crown with a Cross attached.
