Welcome and congratulations, the Old Town canoe with serial number 206734 is a 16 foot long fiberglass Carleton model with a keel that weighed 85 pounds. It was built in March of 1975. The original exterior gelcoat color was red. It shipped on June 17th, 1976 to Little Rock, Arkansas. 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/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 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.
