Originally built in 1930 as a Cloudboy 6F and converted to a 6L in 1933. It was stored during WWII, and after the war it was used as a cropdusting a/c. In 1966 it was restored and marked as a YPT-9B. Only 10 Cloudboys were built. This a/c is currently at the Western Antique Aeroplane and Automobile Museum in Hood River, Oregon.
