I found four pics for C.A. Industries in Portland. I guess the question is, among other things, did they make Duck parts for C.A. Corporation?

It was in the late 1920s when the airplane was first introduced to the people of Valley Stream. In 1928, the Advance Aircraft Corp. opened a flying field for commercial and passenger service. The site was the Reisert farm, located on 270 acres. Hendrickson Bros. graded and constructed the field. Opening day included an air circus (aerial activities). The love affair with the airfield was short-lived. Dust storms, low and night flying, and the noise of roaring engines provoked much criticism from the local residents. Flying restrictions and zoning laws made running the airport very challenging, and in 1930, Curtiss Aircraft purchased the ill-fated airfield, turning it into the largest commercial airfield on Long Island. At the height of activity, over 800 planes flew in and out of the field every day. Charles Lindbergh made Curtiss Field his first headquarters. In 1929, twenty-six women, including Amelia Earhart, gathered at Curtiss Field and formed a women’s pilot organization, The Ninety-Nines. Amelia Earhart, who served as the organization’s first president, suggested the organization’s name reflect the number of original charter members,
By 1933 the Depression had taken its toll - activities had come to a standstill and the airport was closed. The airfield was then purchased by The Columbia Aircraft Corp,a United States aircraft manufacturer. In 1941, Columbia worked closely with Grumman Aircraft, undertaking the development and production of that company's military amphibian aircraft designs, including the J2F Duck. After the completion of wartime contracts for the United States Navy, the firm's operations decreased in scale and Columbia was acquired by Commonwealth Aircraft in early 1946. Commonwealth ceased production of aircraft in March 1947.
