Since the report was compiled, Chicago Bell Advocates spoke with a researcher in Cavezzo, Italy, who found that church bells in Cavezzo were sold to a foundry in Milan in the 1930s in order to be recast for new bells, Schafer said. That was right around the time the Leaning Tower's bells arrived in Niles, so Schaefer believes it is entirely possible that instead of recasting, the bells were sold — and are as old as their dates say.
