How this model was made
Outline traced from Armstrong’s own photos. It has no usable side photo: its rocker and thickness are built from what is known, each said below. The listed thickness is kept, with a boxier cross-section than the default (it fills 89 % of its width × thickness box, against 88 %), to hold the listed volume. The cross-section’s shape is assumed, not measured.
