Before undertaking the long drive, you might ask the seller for the length, and ask for a few photos of the canoe showing details that might help identify the canoe as an Old Town -- deck, shape of bow/stern, and overall appearance to get some idea of the canoe's condition (people are often very optimistic when they describe their own canoe, especially if it is for sale -- one person's "good condition" can be another person's "floating wreck" -- and one person's "needs minor work" is another person's " needs a complete restoration."
If you get pictures, you can post them here -- we love pictures of canoes of all sorts, in any condition.
Good luck, but as always, caveat emptor.
