The information about the Old Town with serial number 72176 is available at
https://www.wcha.org/forums/index.php?threads/12766/ from a request in 2015. The one with serial number 65587 is a 17 foot long, AA (or top) grade, Otca model with Western red cedar planking, open mahogany gunwales, twenty inch mahogany decks, mahogany thwarts, mahogany seats, a keel, and a floor rack. It was built between April and June, 1921. The original exterior paint color was royal blue. It shipped on June 21st, 1921 to Chicago, Illinois. A scan of this build record can be found below.
These scans 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/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 these descriptions don't match your canoes. Feel free to reply here if you have any other questions.
