Paul, the scanned records go up to 241999.
Cecil, the Old Town canoe with serial number 210560 is shown as an 18 feet long Chipewyan built in November 1975, with an aluminum insert as extra equipment, with the original exterior color being avocado, and weighing 76 pounds. It was shipped to Ft. Lauderdale, Florida on December 9, 1975. A scan of this build record can be found by following the link behind the thumbnail images attached below.
[Cecil -- my computer seems to be running into a problem uploading a copy of the build record -- I will try again, or someone else will download it for you.]
This scan and several hundred thousand others were created with substantial grants from the Wooden Canoe Heritage Association (WCHA) and others. A description of the project to preserve these records is available at
http://www.wcha.org/ot_records/ if you want more details. I hope that you will join or renew your membership to the WCHA so that services like this can continue. See
http://www.wcha.org/about-the-wcha/ to learn more about the WCHA and
http://store.wcha.org/WCHA-New-Membership.html to join.
It is also possible that you could have another number or manufacturer if this description doesn't match your canoe.
Feel free to reply here if you have any other questions.

I see that Kathy got an answer to you, with build record, while my computer and the forum kserver were at odds with each other.
