The Old Town canoe with serial number 16583 is a 16 foot long, CS (common sense or middle) grade, HW (Heavy Water) model with western red cedar planking, closed spruce gunwales, ash decks, ash thwarts, ash seats, a keel, and sponsons. It was built between January and April, 1911. The original exterior paint color was dark green. It shipped on April 26th, 1911 to Reading, Penna. It appears to have returned to the factory for repairs on July 6th, 1965. A scan showing this build record can be found by following the link at the thumbnail image 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 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. See

It is also possible that you could have another number or manufacturer if this description doesn't match the canoe. Please reply here if you have any other questions.
