THANK you!
Mrs. Willis Wood is my grandmother. The canoe is in the same family ownership - settled nicely on the Upper Ausable Lake in the Adirondacks, New York. It has been fiber-glassed. (I think my grandmother fiber-glassed all of her boats at the same time. She was a great sailor but was convinced fiber-glass was a good thing after a sailing mishap!)
The mast step must have been removed at that time. We have an old sail and a picture of my uncle sailing I canoe, so I am sure it is the same canoe.
Thank you for your help and I will be glad to send a donation to the WCHA.
