Vintage Otis Escalators at Macy's Union Square in San Francisco, CA Retake

Update: One of the escalators that I think might have been an Otis mod. by ? escalator appears to have since been completely replaced by a Schindler escalator (likely in 2018). I don't know if the other escalators will also be replaced soon.
I don't know for sure, but I am wondering if all escalators are Otis but some of them had some modernization done.
Year installed: 1950s?-1960s?
