Warren,
Canoe #20514 was completed on 4/13/1912 and built as a 16' Charles River in CS (common sense) grade with spruce gunwales and birch seats, decks and thwarts. It had no keel and the original color was dark red. This description does not match with your request...you might want to double check the SN on both stems. A build record is attached for your review.
Canoe #173753 is in fact a 25' War canoe, shipped on 6/18/1964 to Canaan, ME. It was built with a keel, outside stems, floor rack, narrow (2 3/4") planking and the original color was white. Build record attached.
