Congratulations, the Old Town canoe with serial number 80715 is a 17 foot long, CS (Common Sense or middle) grade, HW model with red western cedar planking, open spruce gunwales, birch decks, birch thwarts, birch seats, and a keel. It was built between October, 1923 and February, 1924. The original exterior paint color was dark green. It shipped on March 5th, 1924 to Waterbury, Connecticut. A scan showing this build record can be found below.
This build record 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, join or renew your membership to the WCHA so that services like this can continue. See

It is also possible that you could have another number or manufacturer if this description doesn't match the canoe. The decks, thwarts, and seats were usually all the same type of wood on Old Town canoes but there are some exceptions. Diamond headed bolts had been in use for about a year before this canoe was built. Feel free to reply here if you have any other questions. Good luck with the project,
Benson
