The Old Town with serial number 129018 is a seven foot, six inch long, CS grade, dinghy model with open spruce gunwales, ash decks, spruce seats, a keel, and outside stems. It was built between Januray, 1940 and May, 1941. The original exterior paint color was dark green. It shipped on March 16th, 1942 to Chicago, Ill. The back side of the scan shows that someone from Lakeland, Minn. inquired about this serial number in April, 1982. Scans showing both sides of this build record can be found by following the links at the attached thumbnail images below.
These scans and several hundred thousand others were created with substantial grants from the Wooden Canoe Heritage Association (WCHA) and others. 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 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 your dinghy. The sail rig and floor racks appear to have been added after it left the factory. The information at
http://forums.wcha.org/showthread.php?57 has a good description of how to value and sell an old canoe. Most of this information would apply to your dinghy. Feel free to reply here if you have any other questions. Good luck,
