The Old Town and Carleton canoes with serial number 17323 are both 17 feet long as shown in the records below so neither of those match your canoe. My guess is that you have the Kennebec canoe with this number, especially since there appears to be a faint outline of a Kennebec decal on the deck. This is 16 foot long Kennebec model as shown on page 184 of volume three in the Kennebec ledgers. It was planked by Roy on August 25th, 1923. The canvas covering was applied by Tuttle on September 8th, 1923. Grant applied the first filler coat on the same day. Tuttle applied the second filler coat on September 29th, 1923. It was railed by Webber on the same day. The original color was red. It shipped to location 25-94 on May, 20th, 1925. This location is probably an order number but we don't currently have enough information to identify it.

The Old Town canoe with serial number 91592 is a 17 foot long, CS (common sense or middle) grade, Otca model with red western cedar planking, open spruce gunwales, birch decks, birch thwarts, birch seats, and a keel. It was built between July, 1926 and March, 1927. The original exterior paint color was dark green. It shipped on May 26th, 1927 to Middletown, Delaware.

The microfilms and scans of these records were created with substantial grants from the Wooden Canoe Heritage Association (WCHA) and others. I hope that you will join or renew your membership to the WCHA so that services like this can continue. See

It is possible that you could have another number or manufacturer if these descriptions don't match your canoes. The bow deck, carry handle, and straight thwarts in the Kennebec all appear to be replacements. Feel free to reply here if you have any other questions,
