I asked because when I did a quick Google search there was almost nothing on this building. Maybe my Googling skills are failing me or likely the truth is what you just stated. Which is surprising as it would have been one of the earlier skyscrapers. Found this description from the leasing company:
"This skyscraper, built in 1904-1905 for the Sovereign Bank, replaces a three-story warehouse store. The Sovereign Bank occupied the first two floors. On the upper floors, there were offices for companies, lawyers, notaries, brokers and a consulate. In 1908, it was sold to the Commercial Union Assurance Company, which sold it in 1969 after occupying it for 60 years."
