OT 177607 is a 17 foot Molitor model canoe--- as you know, 17 feet is the standard size for Second Generation Molitors. Your canoe was completed from February of 1967 to March 1968. It has outside stems (standard on this model) and was painted with design #45. It was shipped to Staff Jennings Inc. of Portland, Oregon, on July 16, 1968.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 http://www.wcha.org/wcha/ to learn more about the WCHA and http://www.wcha.org/join.php to renew.
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.
Design 45 is as above-- I don't see a two-tone brown with Greek ends in the Old Town designs... but owners can do whatever they wish. The canoe looks really nice--- love those Molitors, of whatever era...
