Hello Bob--
Old Town 168243 is a 16 foot Otca model canoe, finished November 1958-April 1959, with a keel and sponsons. It was originally painted bright green. Image of the scan of this record is attached below-- click on it to get a larger image.
In this time period, less information is provided on the build record but the trim should be CS grade unless is obviously mahogany. I always find it interesting when sponsons are ordered on a canoe of this vintage-- kind of blasts my theory that sponsons happened because people couldn't swim in twenty pounds of costume and once bathing suits got smaller and people could swim they weren't afraid of the water... but sponsons do work nicely on a sailing canoe. This one has no mention of sail rigging, but if it has been used in that manner then that's why the canoe was ordered with sponsons... or if it has row locks-- it's easier to row a canoe that has sides extended because of the sponsons.
I should have asked if the sponsons were still there-- sometimes they are removed during repairs and not placed back on the canoe. If so, your canoe would still have the little carry thwarts at each end that OT put on their sponson canoes.
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 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.
