Modernization of the interior of the Wiss Building, ten-story landmark office structure at 665-671 Broad Street, Newark, is nearing completion, it is reported by J.I. Kislak Organization, managing agent. The realty firm is coordinating the extensive rehabilitation program with a campaign to being the building to full tenancy.

The structure has been redecorated from top to bottom in modern, color-coordinated style. New elevator cabs have been installed. Every floor has a new lobby, new elevator floor indicators and gates, new lavatory facilities and the latest in fire-protection equipment. New doors have been put on every office. General contractor is Max Drill, Inc., and the work was planned by architect Rudolph Kruger.

TWO NEWARK BANKS provided financing for the renewal program. The Bank of Commerce made available construction funds, and the United States Savings Bank undertook the permanent mortgage financing, Joseph L. Pitman served as consultant.

The Kislak progress report came as heartening news to the more than 150 investor owners, who hope to recoup in time a good portion of their million-dollar investment. They are survivors of a realty syndicate which failed after acquiring the property.

Their ownership firm is now Broad Street Investors Co., with attorneys Samuel S. Saiber and David J. Schapira serving as co-counsel. Officers include Dr. R. John Amato, president; George Pironti, vice president; Benjamin Perlmutter, secretary, and Frank Kulkusky, treasurer.
