The Old Town canoe with serial number 191491 is a 14 foot long fiberglass Carleton model with a keel. It was built in September, 1972. The original exterior gelcoat color was red so the light pink you see now is probably the result of too much time in the sun. Ferro (
http://www.ferro.com/) produced this gelcoat originally but yours sounds like it has faded quite a bit. It shipped on May 25th, 1973 to Westport, Conn. A scan showing this build record can be found by following the link at the attached thumbnail image below.
This scan and several hundred thousand others 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/ot_records/ if you want more details. I hope that you will 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 your canoe. You may want to verify the length and serial numbers again since this one is not 17 feet long. Feel free to reply here if you have any other questions.
