Welcome, the Old Town canoe with serial number 146669 is an 18 foot long, CS (common sense or middle) grade, Otca model with open spruce gunwales, slat seats, half ribs, a keel, and outside stems. It was built between October and December, 1946. The original exterior paint color was dark green. It was shipped on February 27th, 1947 to Devon, Connecticut. The back side indicates that there was a prior request for a copy of this information on June 8th, 1977 from Seymour, Connecticut. Scans showing both sides of this build record can be found below.
These scans 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/catalogs/old-town/records/ if you want more details. I hope that you will donate, join, or renew your membership to the WCHA so that services like this can continue. See

It is also possible that you could have another number or manufacturer if this description doesn't match the canoe. Page five of the 1947 catalog at
