Ron, I can't claim to be an expert on Dundee canoes, but I did look at the one at the Finger Lakes Museum a couple months back. Since it was in a not-well-lit and unheated warehouse, I didn't get to examine it as closely as I would have liked to. But the hull appeared to me to be 3-ply plywood with the two outside faces mahogany. I don't know when this canoe was built, nor the technique used to make it. If that information is available, please pass it along. Tom McCloud.
