If your canoe is an Old Town (as the deck could indicated) the Old Town canoe with serial number 4580 is shown as 16 feet long, CS (common sense) grade, HW model with western cedar planking, spruce gunwales, ash decks, seats, and thwarts. The date stamps on the build record are not readable. The original exterior paint color was dark green. It was shipped to H.B.Crosier in Jackson, Michigan on May 21, 1906. A scan of this build record can be found by following the link behind the thumbnail image attached below.
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 will join or renew your membership to the WCHA so that services like this can continue. See
http://www.wcha.org/about-the-wcha/ to learn more about the WCHA and

It is also possible that you could have another number or manufacturer if this description doesn't match your canoe. The indicated length is different than indicated by the full number you provided.
If that is the case, photographs of the deck, side profile, seats, and other details would be helpful in identifying the canoe. Does the canoe have the typical OT diamond head bolts?
