The Old Town canoe with serial number 6538 is a 16 foot long, CS (Common Sense or middle) grade, Charles River model with white Maine cedar planking, a keel, maple decks, maple thwarts, maple seats, closed spruce gunwales, and spruce (finish or outside) rails. It was built in April, 1907. The original exterior paint color was dark red. It shipped on April 30th, 1907 to Jackson, Michigan. A scan showing this build record can be found below.
This scan 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/catalogs/old-town/records/ if you want more details. I hope that you will donate, 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. The sponson line appears to be blank. I checked the records for numbers 16538, 116538, and the 6538x range but didn't find a better match. Can you provide some pictures of the serial numbers from both ends and the interior of the canoe? Feel free to reply here if you have any other questions. Thanks,
Benson
