This is a sure match! Old Town 163541 is a 25 foot CS (common sense, or not the fancy mahogany) War canoe. It has a keel, outside stems (the oak strip at either end of the canoe that protects the canoe when campers blast headlong into the dock) and a floor rack. It was painted dark green and shipped to Joseph Tinker at Christ Church Camp, Winchendon, MA.
The scan of this record is attached below. Scans of approximately 210,000 records were created with substantial grants from the Wooden Canoe Heritage Association (WCHA) and others. Additional information about the project to preserve these records is available at http://www.wcha.org/ot_records/ if you want more details.
