Hi--
Check the numbers at both ends, and post pictures if you want extra eyes looking at the serial number-- it also helps to see the canoe. I checked all the canoes beginning with 136270 and there is only one 16 footer-- I'll give you the list:
136270 17' Otca
136271 18' guide
136272 20' guide
136273 18' sq end paddling canoe
136274 17' Otca
136275 15' 50#
136276 18' sq end paddling canoe
136277 13 1/2' lapstrake
136278 13 1/2' lapstrake
136279...
Old Town 136279 is a 16' CS (common sense or middle) grade Yankee model canoe with open spruce gunwales, ash decks, ash thwarts, ash seat frames, a keel, and a floor rack. It was originally painted design #43. It was shipped to Dover, NH, on April 2, 1943.
Does the trim match? Does this canoe appear to be a war-era Yankee? It's fun to figure these things out! The scan is posted below-- click to see a larger image.
This scan 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 canoe. Feel free to reply here if you have any other questions.
