Hi Tim-- I'll give you both records, but neither is for a guide model.
91418 is a 17 foot CS (common sense) grade HW model canoe finished between June 1926 and February 1927. It has red Western cedar planking, open spruce gunwales, birch decks/thwarts/seat frames and a keel. It was painted dark green and shipped to San Francisco, CA on March 2, 1927.
91413 is a 17 foot AA (top) grade Otca canoe, finished from June 1926 to March 1927, with open mahogany gunwales, mahogany decks/thwarts/seat frames, a keel and a floor rack. It was painted design #28 and shipped to Chicago, IL, on March 30, 1927.
It should be fairly easy to determine which of these two records is the correct one for your canoe. Otcas had 20 inch decks with coaming in those days, and the mahogany trim is a big difference too. Or, your canoe could be neither of these, and we can keep looking.
If your canoe is the Otca, I'll post a picture of design 28.
Scans of these records are attached below-- click on them to get a larger image. These scans and several hundred thousand others 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 join or renew your membership to the WCHA so that services like this can continue. See
