NACA-TR-563 (1937). NTRS abstract: 54 pressure orifices, a 5-by-30-inch model, 17 angles from −20 to 30 degrees, Reynolds number approximately 3 million; comparison with potential-flow calculations.

NACA Report 460, originally published November 1933; primary PDF: ntrs.nasa.gov/api/citations/19930091108/downloads/19930091108.pdf . Apparatus and Methods describes duralumin models, dimensions, Reynolds number, tank pressure and measured forces/moments. The introduction and profile derivation explain systematic variation of thickness and mean-line form.
