The Old Town canoe with serial number 148674 is a 16 foot long, CS (Common Sense or middle) grade, HW (heavy water) model with red western cedar planking, open spruce gunwales, a keel, outside stems, and sponsons. It was built between May and September, 1947. The original exterior paint color was light Yale blue. It shipped on May 17th, 1948 to Philadelphia, Penna. 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. 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. Canoes with a family history are especially nice. Feel free to reply here if you have any other questions. Good luck with the restoration,
