Hello, Dennis--
You may have Old Town 160757, in which case the "F" or "T" is a "1"... Old Town placed a space between the serial number and a number listing the length of the canoe. If your canoe is 18 feet long, this may be the correct record. After reading the details of the build record, if they don't seem to fit or if you are unsure, post a picture and we may be able to help determine what you have.
Old Town 160757 is an 18 foot long CS (common sense, or middle) grade Guide model canoe that was completed September-December of 1953. The canoe was fitted with a keel and painted guide special green. The wood species of decks, thwarts, and seat frames is not specified, but CS grade means that any hardwood other than mahogany was used. I've seen oak used more commonly on Guides than on Otcas and HWs, but it could also have been ash or birch or maple. Post a picture if you aren't sure of the wood species.
This canoe was shipped to Nash Marine Supplies in Washington, DC, on May 25, 1955. There's no mention of a sail rig on the build record, but the dealership could have added that. 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.
