Dan,
Yes, this was on Ebay, although the bidding expired without a sale. I went on the DragonFly website and there wasn't any additional info that I didn't already have. All I really know about this Rhinelander canoe is Rhinelander Boat Company started in 1903. I hoping that there is some WCHA member out there might have more information as to the styles that they made, and years produced. Just for your information, it has all mahogey decks, thwarts, seats and inner and outer rails.
I have repaired canoes in the past, but this one will be a challenge as most of the center ribs are broken along the tumblehome. If you have any input on how to repair without losing the shape of the hull, I'd appreciate it.
Rick
