What year were the bell tower chimes installed

Quick question: during our 5:30 p.m. lobby welcome, we tell guests the bell tower by the West Garden dates to 1958, but an old facilities tag reads 1961. Can anyone confirm the correct year so our team stays aligned and our guest story stays accurate?

And pretty sure it’s split: tower built in 1958, chime mechanism added in 1961 after the West Garden electrical upgrade. @Facilities, can you confirm whether that tag is on the amp rack or the bell housing so we can say “tower 1958, chimes 1961” at the 5:30 p.m. welcome?
