More impressed that it's a Westinghouse escalator - which means it's not been updated since at least 1989.

10 Rockefeller Plaza was built in 1940 so the escalator could be original.

The London Underground replaced its last wooden escalator only 11 years ago and that was more than 80 years old.

(I should clarify: the treads were wooden but the mechanism was steel.)

Wynyard Station in Sydney turned their wooden escalator into art, which I would was neat. https://www.transport.nsw.gov.au/programs/transport-arts/int...

Like the ones at Macy's 34th Street Herald Sq NYC

I bet it would be outrageously expensive to replace. Escalators aren't cheap to begin with and this one is no doubt built to its own standard so anything you replace it with would have to be heavily customized to fit.
