Hello. Your canoe is a 16' CS Grade (Common Sense or Middle Grade) Yankee model with open spruce gunwales. It was built in 1940, equipped with a keel, painted dark green and shipped to Providence, RI.
The scan of this record is attached -- 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 and anyone else reading this will join or renew membership in 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.
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. Providing photographs would help with identification, as would an accurate measurement of the boat's
