The Old Town canoe with serial number 18930 is a 16 foot long, AA (or top) grade, Charles River model with red western cedar planking, open mahogany gunwales, mahogany decks, mahogany thwarts, mahogany seats, half ribs, mahogany outside finish rails, a keel, and outside stems. It was built between October, 1911 and April, 1912 The original exterior paint was dark red. It first shipped on April, 19th, 1912 to Quebec but was returned on September 1st, 1913. It was reshipped to another location on September 9th, 1913 as noted on the back of the card but that was not scanned. A scan of the front side of this build record can be found by following the link at the attached thumbnail image 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. See
