It was built between November, 1911 and June, 1912. The original exterior paint color was slate. It shipped on June 17th, 1912 to Altoona, Penna.

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 this canoe could have another number or be from a different manufacturer if this description doesn't match your canoe. Feel free to reply here if you have any other questions.
