The Old Town with serial number 177930 is a 15 foot long light weight model with a keel and a painter ring. It was built between April and June, 1967. The original exterior paint color was dark green. It shipped on June 14th, 1967 to Grand Rapids, Michigan. A scan of 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 as you probably know well. 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

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.
