Hi Tom--
Old Town 170669 is a 16 foot Guide model canoe finished between December 1960 and May of '61. The grade of the canoe isn't specified, but the Guide model was often GS or Guide Special grade, and the wood species for decks and thwarts would be a hardwood other than mahogany... ash, birch, or oak. I've noticed oak appears on the records of GS grade canoes more often than it does on CS grade.
Your canoe was fitted with thwarts instead of seats, has a keel, and was originally painted aluminum. It was shipped to Camp Lutherlyn, Red Cross Aquatic School, in Prospect, PA on May 31, 1961.
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 and anyone else reading this will join or renew membership in 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 your canoe. Feel free to reply here if you have any other questions.
If this is the correct record, it's interesting that someone thought it was a Peterborough... the story is usually the other way around, with someone convinced they have an Old Town when they actually have a boat by another builder.
