Bishop Paper
Paper company operated by Preston Meeker Harrington Sr (1871-1942), Preston Meeker Harrington Jr (1904-1980), and possibly members of the Clement family.
The obituary for Preston Meeker Harrington Sr (1871-1942) mentions that he was "...for many years president of the Bishop Paper Company at 7-11 Laight Street, Manhattan..." and that he "...became associated with an old New York paper firm, Clement & Stockwell, owned by relatives. This firm later became the Bishop Paper Company." Another obituary describes him as "president, treasurer, manager, and director of the Bishop Paper Company" and mentions that it "...was the firm of Clement and Stockwell when he first entered its employ."
A wedding announcement (1939) for Daniel W Harrington (1903-1958) and Hortense Yule (1903-1996) says that Daniel is secretary of Bishop Paper.
Jesse B. Clement (1842-1914)'s obituary mentions that Clement & Stockwell was then located at 50 Beekman St in New York. Other sources (including the company's own promotional materials) say 30 Beekman St.
A New York City directory from 1876 shows Duane Howard Clement (1846-1908) as working at the business.
History
Clement & Stockwell was previously run by Jesse B. Clement (1842-1914), uncle of Preston Meeker Harrington Sr (1871-1942).

Jesse B. Clement sued a customer over $5379.72 (equal to around $151k in 2021) in unpaid bills and won, in a jury trial.
Trow Press lawsuit, 1914
In 1914, Clement & Stockwell sued a customer, Trow Press, for non-payment on an order of paper used in printing a book for the Royal Baking Powder Company. Trow claimed poor quality paper, but apparently didn't mention the problem until months after receiving the order. The suit seems to have been appealed back and forth and it's not clear who ultimately won. The documentation includes court transcripts with testimony by Preston Meeker Harrington Sr (1871-1942). See "Clement & Stockwell vs. Trow, 1914".
In Harrington's testimony he says that he was treasurer at Clement & Stockwell at the time.
Wood Pulp News, December 25, 1915
"Wood Pulp News" carried this story in its December 25, 1915 issue:
Following Jesse B. Clement's death, Messrs Bishop and Ross of the Clement & Stockwell company left to form a new company, taking "...practically the entire office and store force..." to the new company. Clement & Stockwell was at the time controlled by Clement's estate.
The Paper Record, January 1918
The January 1918 edition of "The Paper Record" lists Clement & Stockwell products and prices on pages 24B and 25B. It says "Our 46th Year in this Location" at 30 Beekman St. So they had been at that location since 1872-- possibly at other locations before?

Laight Street Building
The location on Laight St. mentioned in Preston Sr's obituary can be seen in this photo of an unknown striker:
The subway entrance is labeled "8th Avenue". This refers to the IND 8th Avenue Line of the New York subway system. The entrance leads to the north entrance of the Canal Street station.
The location is in Tribeca near the Holland Tunnel. The building is across the street from what is now Albert Capsouto park. The park space was a parking lot when Bishop paper was there.
