My guess is that you may have the Old Town with serial number 139737. This is a 16 foot long, CS (Common Sense or middle) grade, double ended boat model with open spruce gunwales, ash decks, ash thwarts, ash seats, a keel, a floor rack, and a bob stay. It was built between April and June, 1944. The original exterior color was dark green. It shipped to Ashland, New Hampshire on July 21st, 1944. A scan of this build record can be found below.
This scan 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/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 to learn more about the WCHA and

It is also possible that you could have another number or manufacturer if this description doesn't match. See
https://www.wcha.org/forums/index.php?threads/17826/ for a similar record. Does this boat have outside stems? The record for number 139736 is another double ended boat which has them. Can you get a picture of the serial number from the other end? Feel free to reply here if you have any other questions.
