How this model was made
Outline traced from Armstrong’s own photos, rocker and thickness from its side view. Straight from the photos it held 66.7 L (+3 %). The side view reads the listed thickness, so the photo’s thickness is kept, with a rounder cross-section than the default (it fills 86 % of its width × thickness box, against 88 %), to hold the listed volume. The cross-section’s shape is assumed, not measured.
