Old Town 172006 is a 16 foot Guide model canoe completed April to June of 1962, with half ribs and outside stems. (In this time-period, Old Town no longer classified canoes in different grades.) The canoe was originally dark green (which appears still to be the case.) It was shipped to Englewood, CO, on June 6, 1962-- so it just had a birthday! The details on this record appear to match your canoe-- I see the half-ribs and outside stems.

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 athttp://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. Feel free to reply here if you have any other questions.
More information on the Old Town Company can be found in Sue Audette's book "Old Town, Our First Hundred Years", which is available through the WCHA store and most booksellers, eBay, Amazon, and public libraries.
