The Old Town canoe with serial number 123020 is an 11 foot long, CS (Common Sense or middle) grade, fifty pound model with open spruce gunwales, ash decks, and a keel. It was built between September, 1937 and January, 1938. The original exterior paint color was dark green. It was shipped on July 9th, 1938 to Milwaukee, Wisconsin. A scan showing 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/ot_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. Feel free to reply here if you have any other questions,
