The Connections Museum in Seattle has one of these in operation (as well as other generations of mechanical and electronic switching) which is amazing to see and hear in person.

Here's the No. 5 Crossbar: https://www.youtube.com/watch?v=XKyXCZV_faY

The whole museum is absolutely worth repeated visits.

I haven't seen anything from the Connections Museum to indicate they have any non-Bell CO stuff on display. Where are you seeing that they have an ITT/Pentacosta switch?
