The collection contains Bilek’s aviation research notes, including newspaper and journal articles, handwritten notes, drawings, and photographs, some glued to paper. The photos and notebook are predominantly Curtiss aircraft. The three boxes of the collection represent the Bilek’s original order in three binders. Box 1 is primarily commercial planes, 1920-1940. Box 2 contains L.T.A. A-GYRO and Unusual & Europe. And Box 3 is primarily Curtiss planes photos & engineering cost figures. Box 2, page 55, to Box 3, page 28, appear to be a collection of primarily experimental aircraft with photos.
