Dan,
What we also would like to know:
-type of screws, slotted, phillips, square? (Slotted says U. S. made.)
-photos, resized of course so they fit. click on Manage attachments below and browse for wherever you stored them on your computer. Pics of decks, stem, seats, thwarts, the details.
-type of wood if you know.
If you rap on the side with your knuckle the canvas sounds diferent than 'glass. Canvas is more of a thud. 'glass has more of bang to it. 'glass is more musical than canvas. Or you could just unscrew one of the gunnels to be sure. For small hairline cracks it probably is canvas. Sand with 220 and paint and paddle. 'glass canoes tend to be heavier also. Planking could be as thin as 1/8" With 1 1/2" rib width, I'd guess you have a canadian canoe.
I am not good at identification but if you post with more info, you'lll find out how smart some of these guys are.
Regards,
Cabin fever Dave.
