Welcome, the Old Town canoe with serial number 120685 is a 16 foot long, CS (common sense or middle) grade, HW (heavy water) model with open spruce gunwales, birch decks, birch thwarts, birch seats, and a keel. It was built between February and May, 1937. The original exterior paint color was dark green. It was shipped on June 1st, 1937 to Flint, Michigan. 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. 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, join or renew your membership to the WCHA so that services like this can continue. See https://www.woodencanoe.org/about
