John: The Old Town canoe with serial number 87477 is a 16 foot long, CS grade, HW model with open spruce gunwales, birch decks, thwarts, and seats with a keel. It was built between March and April, 1925. The original exterior paint color was dark green. It shipped on May 5th, 1925 to Chicago, Illinois. A scan of this build record can be found by following the link at the attached thumbnail image below.
This scan was created with substantial grants from the Wooden Canoe Heritage Association (WCHA) and others as you probably know well. 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/ to learn more about the WCHA and http://www.wcha.org/join.php to join or renew.
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.
