I can't see any references to the company itself, however there a number of newspaper articles mentioning the address - around the 1940s seems to be insurance companies eg "Moffat and Atwood" (1949), "Maryland Insurance Co of Delaware" (1944), "Protective Indemnity company" (1944), "Niagra Fire Insurance Co" (1942), "Fidelity Phoenix Fire Insurance Co" (1936), "Alfred A Peck Insurance Co" (1935). Many more.
