Hi Jamie,
Old Town sold directly to the consumer, and my guess is that Otis Wright wasn't a dealer. It would be very cool to talk with the family and maybe get pictures of the canoe when it was first purchased.
Does the canoe need new seat frames, or only the cane part? If it needs new frames, most people restoring canoes build them themselves, using the old seat or another from the same era as a template (you can always find someone in the group here who has a canoe of the same vintage-- especially if it's an Old Town!). If it's only the cane that needs replacing, you can replace the cane yourself. Your canoe probably has hand-caned seats, although it was shipped about the time Old Town switched to sheet cane so I can't be sure. Hand caning is done through holes in the frame, and sheet cane is machine-woven, and is held in place with a spline.
Use the "search" function above and type in "cane" for a recent discussion of seat caning. Ask for help if you are stumped. Replacing cane isn't heavy-duty woodworking, as replacing a D-shaped outwale may be! Don't let any of this overwhelm you, because you can post about it here in Forums.
One mistake some people make is to remove a seat because the cane is broken and replace the entire seat with a new one. Huge mistake, for a number of reasons--- especially if the original seat is mahogany, as in your case.
Fasteners--- post here about your needs... check eBay... someone will jump in and say where they found what you need. You can also check the main page of this website for "builders and suppliers".... and check the list of WCHA chapters to see if you live near a chapter. You may live a few miles from another member.
Old Town decals are available through the WCHA Store.
I doubt if there's any ash on your canoe. It's AA grade, which means the trim is all mahogany-- the rails are mahogany, the thwarts are mahogany and the seat frames are mahogany. The hull of nearly all wood-canvas canoes (by any builder) is cedar--- on yours, the planking is red cedar and the ribs are white cedar.
I believe Old Town did make their own paddles--- if you post a picture, someone may be able to tell you if it's likely to be an Old Town paddle.
A good reference for anyone new to wood/canvas canoes is Stelmok and Thurlow's "The Wood and Canvas Canoe."
I hope this helps--
Kathy
