The Old Town canoe with serial number 83375 is a 17 foot long, AA (or top) grade, Otca model with red western cedar planking, open mahogany gunwales, mahogany decks, mahogany thwarts, mahogany seats, and a bang plate along the full length of the keel. It was built early in 1924. The original exterior paint was similar to the one shown at
http://www.wcha.org/catalogs/old-town/designs/design06.gif which was known as the design number 6. It shipped on March 15th, 1924 to Scranton, Penna. A scan showing this build record can be found by following the link at the attached thumbnail image 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/ot_records/ if you want more details. I hope that you will 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 your canoe. Feel free to reply here if you have any other questions,
