Welcome and congratulations, the Old Town with serial number 87036 is a 16 foot long, AA (or top) grade, speed square stern model with red western cedar planking, open mahogany gunwales, mahogany decks, mahogany thwarts, mahogany seats, a keel, outside stems, a floor rack, and sponsons. It was built between February and April, 1925. The original exterior paint color was dark green. It shipped on May, 6th, 1925 to Lincoln, Maine. A scan showing this build record can be found by following the link at the attached thumbnail image below.
This scan and several hundred thousand more were created with substantial grants from the Wooden Canoe Heritage Association (WCHA) and others as you probably know well. A description of the project to preserve these records is available at
http://www.wcha.org/catalogs/old-town/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-wcha to learn more about the WCHA and

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.
