Moisture Resistant Finishes for Airplane Woods
This 1921 technical report, issued through the NASA Technical Reports Server, documents tests on moisture-resistant finishes for wood used in early airplane construction, written for aircraft engineers and materials researchers. The pictures are plain photographic and graphical records: a rotated photograph of a worker applying a coating to a long timber plank, and a bar chart plotting moisture absorbed in grams per square foot over 17 days across lettered finish samples, useful to a designer as a model for clean, dense data-bar layouts.
