If you do a search for "Crandell" on these forums, you'll get several hits. I don't think there are any records of build dates for these, as there are for Old Towns & Kennebecs, but others here may have some insight into that. I don't see anything for Crandell in the Knowledge Database, but that's probably because nobody got around to writing it yet. It's an opportunity!
As for what its worth, here's a thread that discusses value:

Welcome to the WCHA! You'll find that folks here are very willing to share their restoration techniques & experience. Depending on your location, you may be able to find a local chapter; look here:
http://www.wcha.org/local-area-chapters/ You'll find good eyes-on advice, and very possibly some hands-on help.
There are two books that can help guide you through restoration & repairs:
http://store.wcha.org/The-Wood-and-Canvas-Canoe.html is often referred to as "the Bible" of canoe repairs, but is out of print. You may be able to find it on eBay, Craig's List, or through your public library.
The other is "Building the Maine Guide Canoe," by Jerry Stelmok, but I don't see it listed in our store anymore... Not sure what's going on there.
In the WCHA store, there are also reprints from Wooden Canoe, our bimonthly journal, about rebuilding canoes.
From what I can see in the pictures, the boat looks very restorable. Posting pictures is highly encouraged, especially when you have questions. Remember that the only "dumb question" is the one you decide not to ask -- folks here have restored a lot of old canoes, and are more than willing to help guide you through the process. Even if nobody has seen a particular issue before, you'll get a lot of great ideas how to approach anything.
We like pictures of wooden canoes, in all stages of restoration... especially the part when they get back on the water!
