The Old Town canoe with serial number 86672 is an 18 foot long, AA (or top) grade, Otca model with red Western cedar planking, open mahogany gunwales, thirty inch mahogany decks, mahogany thwarts, mahogany seats, half ribs, a keel, outside stems, bilge keels capped with brass, mahogany rub rails capped with brass, and a bang plate along the full length of the keel. It was built between January and June, 1925. The original exterior paint design was similar to the one shown at
http://www.wcha.org/catalogs/old-town/designs/design22.gif which was know as the design number 22. This also had the name "Ethel-Dorth" in two inch high letters on the right and left sides of the bow. It shipped on June, 9th, 1925 to Bridgeville, White, in Warren County, New Jersey. A scan showing this build record can be found below.
This scan and several hundred thousand more were created with substantial grants from the Wooden Canoe Heritage Association (WCHA) and others as you probably know well. 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. Please provide some pictures if the original design is still showing. Feel free to reply here if you have any other questions.
