The Old Town with serial number 117500 is a 16 foot long Yankee model in CS (Common Sense or the middle) grade with red western cedar planking, open spruce gunwales, oak decks, oak trim, and a keel. It was built between March and June, 1936. The original exterior paint color was dark green. It was shipped on July 8th, 1936 to High Falls (?), New York. A scan of this build record can be found by following the link at the attached thumbnail image below.
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/wcha/ to learn more about the WCHA and http://www.wcha.org/join.php to join.
It is also possible that they 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.
