The Old Town with serial number 23696 is a 16 foot long double end boat model in CS (Common Sense or the middle) grade with red Western cedar planking, open spruce gunwales, oak decks, oak thwarts, oak seats, open spruce outside gunwales, a keel, and outside stems. It was built between October, 1912 and May, 1913. The original exterior paint color was dark green. It shipped on June 5th, 1913 to Newburgh, New York. A scan showing this build record can be found below.
This scan 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 or renew your membership to the WCHA so that services like this can continue. See https://www.woodencanoe.org/about to learn more about the WCHA and https://www.woodencanoe.org/shop to donate or join.
