This is clearly not the Old Town with serial number 757747 or 157747 (in spite of the modern brass tag on the deck). It could be either 151741 or 157147. My guess is that the correct number is 157147. This is a 17 foot long, AA (or top) grade, Otca model with open mahogany gunwales, a keel, outside stems, and a floor rack. It was built between February and April, 1952. The original exterior paint color was similar to the one shown at
http://www.wcha.org/catalogs/old-town/designs/design37.gif which was known as the design number 37. It shipped on April 14th, 1952 to Framingham, Mass. The back side of this record shows that there were previous requests for a copy of this build record from Brattleboro, Vermont in May of 1977 and from Putney, Vermont in July of 1989. Scans of these build records can be found by following the links behind the thumbnail images attached below.
These scans and several hundred thousand others 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 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. Feel free to reply here if you have any other questions. Good luck,
