Otis Mod. by ? Traction Elevators (Innovation Fixtures) at Oliver Building in Pittsburgh, PA

This building was built in 1908-1910. According to a historical Otis ad, the original elevators were Otis. These elevators have received many modernizations and/or replacements over the years:
Otis manually-controlled (original)
Otis Signal Control (1st mod)
Otis Autotronic (2nd mod)
Otis? mod with Innovation fixtures (3rd mod)
Otis Compass destination dispatch (4th mod, low rise/office bank only)
This building has a low rise bank (not shown in video), and a high rise bank. The low rise floors are office space, and the high rise floors were converted to a hotel (Embassy Suites). The 25th floor is the hotel lobby, and a restaurant/bar.
The hall stations are Otis hall stations. I suspect these were replaced sometime after the Innovation fixture mod, though I don't know for sure.
The door sills are very rare. They are NOT labeled Otis. I am guessing they either date from the Signal Control mod (although it is very rare for an Otis door sill to not be labeled Otis, with the exception of newer installs from the 1990s or so and later), or another modernization that wasn't done by Otis.
These elevators received some upgrades c. 2022, including new cabs, and the same COPs but new buttons (newer "clicky" Innovation buttons), and possibly new car indicators (they are red dot-matrix displays now instead of green)
