Before the wing, a high racing stroke was supposed to keep the blade close to the hull. The wing moves out. Both are vertical strokes. There are plenty of videos of the wing stroke. Can anyone point me to a video of a properly executed racing euro stroke?
Tough request
Wing paddle was introduced in the 80s, the kayak historians will correct me if I am wrong. You need older footage which is a little tougher to find.
Anyways, try u-tube 
This link has some,

blade close to hull
Thanks for the link. If you look closely, you can see how the blade remains very close to the hull. Very different than a modern wing stroke.
