CH 129c

Thus far we have this classification showing up specifically in connexion with wing warping. We also have this classification used in connexion with propulsion, though also here still in connexion with wings and likely flapping. In any case, though we may determine this classification as being broadly connected to wings, it is still distinguished from CH 115, a Swiss aero-classification which factors greatly into our data. A complete outline of the antique patent classification system will, as always, shed light on these things.
