Welcome, the Old Town canoe with serial number 214203 is a 17 foot long Chipewyan Tripper model with aluminum inserts in the rails that weighed 76 pounds. It was built in June, 1976. The original exterior color was green. It shipped on March 30th, 1977 to Anchorage, Alaska. A scan showing this build record can be found below.
This scan and several hundred thousand more 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/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 https://www.woodencanoe.org/about to learn more about the WCHA and https://www.woodencanoe.org/shop to donate or join.
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.
