The Old Town canoe with serial number 116558 is a 17 foot long, CS (Common Sense or middle) grade, HW (heavy water) model with red Western cedar planking, open spruce gunwales, oak decks, oak thwarts, oak seats, a keel, and sponsons. It was built between November, 1935 and March, 1936. The original exterior paint color was similar to the one at
http://www.wcha.org/catalogs/old-town/designs/design37.gif which was known as the design number 37 with “Orange color instead of fire red.” It shipped on May 19th, 1936 to Long Island City, New York. It was returned on October 22nd, 1936 for refinishing. If you really have a 16 foot long square stern then it may actually be serial number 116553. Scans showing both of these build records can be found by following the links at the attached thumbnail images 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. Feel free to reply here if you have any other questions.
