This is just a quick post to show the construction methods used by Supermarine on their wooden aircraft hulls. The photo is of a Supermarine Southampton Mk. I. The Supermarine Nanok was designed and built right after the Southampton. It is quite safe to assume that most of the design techniques used on the Southampton were reused on the Nanok. Note how the planking is immaculate, with every plank attached with brass screws to the underlying skeleton. It is also worth noting the construction of the metal parts.
