Wow -- you hit the lottery indeed. Everyone who reads your post and sees your pictures is going to be jealous. It is great that someone with the right instincts happened upon this boat before the chainsaw/funeral pyre crowd had their way. Not only did you get a basically free canoe, but you get brownie points for a charitable contribution and for preventing a canoe-acide.
From the photos, you have a canoe that will quite readily be restored, probably with a minimum of trouble. Its hard to evaluate all the wood from photos, but it looks in pretty good shape. One of the stems seems to need a little work, and the old varnish should be stripped and re-done. The canvas, of course, needs replacement, and then you will have the opportunity to paint it in the color(s) and design you wish. Poke around these forums -- you will see photos of all kinds of restored canoes -- with one-color elegance through baroque exuberance.
Again, from the photos, it is not clear that this canoe had floorboards (duckboards) -- boards running the length of the canoe. Such are not structural -- some people like them because the protect the wood and varnish of the interior from feet and baggage, and will help keep baggage (or picnic lunches, etc.) if (when) water gets in the canoe. Others think they are bothersome, burdensome appendages. If you want them, they are easy enough to make, even if your canoe never had them. As with finishing the canoe -- ya pays yer money, ya makes yer choice.
There are a couple of things to do just to start. First go to
http://dragonflycanoe.com/id/ where you will find some basic information about Carlton Canoe and the relationship to Old Town Canoe.
Next, you should do some reading -- Before making any decision about how to repair or restore your canoe, you would do well also to get, or at least look at, "The Wood and Canvas Canoe: A Complete Guide to its History, Construction, Restoration, and Maintenance" by Rollin Thurlow and Jerry Stelmok, and/or "Building the Maine Guide Canoe" by Jerry Stelmok, and "The Old Town Canoe Company" by Susan Audette and David Baker.
The first is often called the "bible" of canoe repair, restoration, and maintenance; the second is an excellent study of the wooden/canvas canoe, and the third is a great history of the company and its canoes. These are available from the WCHA store, are often on eBay, or from Amazon. Sue Audette also sells her book directly (
http://www.thebaglady.tv/ ).
And as you are learning, the WCHA and these forums are a great resource -- don't be bashful about asking questions -- someone here will likely have the answer -- maybe even two or three different answers.
And very important, as you proceed with restoration -- photos. We all love photos, just because we all love wooden canoes, but also because most of us have things to learn, and photos of what other people do and how they approach a task are a great sources of information.
You clearly have been bitten by the bug -- the only thing you have to watch out for is to keep the resulting disease under control.
