The Old Town with serial number 118640 is a 12 foot long, AA (or top) grade, special square stern model that was built on the fifty pound model's form. It has red Western cedar planking, open mahogany gunwales, mahogany decks, mahogany thwarts, a keel, and a floor rack. It was built in July, 1936. The original exterior paint color was dark green. It shipped on July, 28th, 1936 to Peterborough, New Hampshire. I remember looking at this for a long time but couldn't decide how I would ever use it.
The Old Town canoe with the serial number 198834 is a 17 foot long Otca model with a keel that was built between January and March, 1974. The original exterior paint color was dark green. It shipped on March 27th, 1974 to Madison, Wisconsin. The back side shows that it was damaged and came back for repairs on March 22nd, 1976. It was fixed and shipped to Newbury, Massachusetts on December 16th, 1976. It was purchased on March 12th, 1977 and the warranty card was returned from Haverhill, Massachusetts. Scans showing these build records 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 join or renew your membership to the WCHA so that services like this can continue. See
http://www.wcha.org/about-wcha to learn more about the WCHA and

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.
