This is a rather neat bit of woodwork.
And, while obviously a wing section, it's also rather unusual as it is a foreplane, and as you'd expect in this thread, was the one built for the Boxkite.
One of the things that makes the Boxkite very unusual is the pitch control with this foreplane and an elevator, and the fact that, as well as the wings, it has a forward lifting surface (the controllable foreplane) and a (biplane) lifting-surface tail unit. Adds a little interest to lift calculations, I'm sure.
