You may want to check that number again... both stems. Old Town 164027 comes up as a 15 footer, not a 16 footer. It's a CS grade fifty-pounder shipped October 20, 1955, to Paducah, Kentucky.
The scan of this record is attached below-- click on it to get a larger image. 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 renew.
As I said, this doesn't appear to be the correct record, if your canoe is a 16 footer... we can try again.
