One bell was installed for the 1971 stadium opening at the 400 level in center field and, with the animatronic mascots Phil and Phillis, were part of a display that rang after a Phillies player hit a home run. This bell, whose whereabouts the team said are now unknown, was the one hit by Phillies slugger Greg Luzinski off Burt Hooton in 1972. The entire display was dismantled in the late 1970s.
