The Boeing Model 1, also known as the B & W Seaplane, was a United States single-engine biplane seaplane aircraft. It was the first Boeing product and carried the initials of its designers, William Boeing and Lt. Conrad Westervelt USN. The two B & Ws were offered to the United States Navy. When the Navy did not buy them, they were sold to the New Zealand Flying School and became the company's first international sale. On June 25, 1919, the B & W set a New Zealand altitude record of 6,500 feet. The B & Ws were later used for express and airmail deliveries, making New Zealand's first official airmail flight on December 16, 1919. The two B & Ws were offered to the United States Navy.
