Very interesting - thank you! My great-grandfather bought this canoe in Houston around that same time (late 30's - early 40's). He took good care of it, and then at some point, I am told my great-uncle re-covered the exterior with fiberglass. It is true there is some sort of clear, hard coating on the exterior, but the mat underneath appears to be one continuous piece. I don't know how you would do this unless it's the original canvas or a new, single piece of canvas per side. The color is still dark green.
The wicker seats must have been re-worked at some point because the wicker looks almost perfect.
