The Carleton serial number 14646 was issued twice. The first one is an 18 foot long, regular (or middle) grade, Carleton model with red Western cedar planking, open spruce gunwales, birch decks, birch thwarts, birch seats, and a keel. It was built between March and May, 1920. The original exterior paint color was N. H. (New Haven railroad) green. It shipped on May 18th, 1920 to New York City. The second one is probably the one you are seeking. It is an 18 foot long, regular (or middle) grade, Carleton model with red Western cedar planking, open spruce gunwales, and a keel. It was built in 1920. The original exterior paint color was light green. It shipped on May 25th, 1920 to Toledo, Ohio. Scans showing both of these build records can be found below.
These scans 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 this description doesn't match the canoe. The new members' area on the main site has all of the catalogs from the CDs you are offering. Feel free to reply if you have any other questions.
