My wife and I recently purchased a 1920's St. Louis Meramec and we have been out paddling it a few times already.  We are enjoying the old canoe a lot.  We have some wood paddles but they're brand new and they just don't seem/ feel right sitting next to the canoe.  I haven't found much on the history of paddles.  Is there such a thing or have there always been so many variations that there is no sequence to speak of?  What might paddles from that era looked like?
