The Old Town canoe with serial number 180718 is an 18 foot long Otca model with a keel. It was built between May and September, 1968. The original exterior paint color was dark green. It shipped on June 26th, 1969 to Saint Paul, Minn. The back side of the record shows that it may have moved to Minnetonka, Minn. by 1983 when there was a pervious request for a copy of this build record.
Scans showing both sides of this build record can be found by following the links at the thumbnail images attached below. These scans 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.
