The Old Town canoe with serial number 174709 is a 17 foot long Molitor model with narrow two and three quarter inch planking, a keel, and outside stems. It was built between March and April, 1965. The original exterior color was white and red. It shipped to Amesbury, Massachusetts on April 19th, 1965. A scan showing this build record is attached below.
This scan and several hundred thousand more were created with substantial grants from the Wooden Canoe Heritage Association (WCHA) and others as you know well. Your lifetime membership is much appreciated.
It is possible that you could have another number or manufacturer if this description doesn't match the canoe. Please share a picture if the original paint design is still showing. Feel free to reply here if you have any other questions.
