It would be helpful if you could post some pictures of the serial numbers from the other end since the one shown so far appears to be 17 x00x9 which leaves a lot of options. Kennebec is the only builder listed at
http://wcha.org/legacypages/maine-list.htm from Waterville, Maine. The Kennebec canoes with serial numbers 10049 and 100049 have no indications of being built with long decks. However, Kennebec worked with Morris in the 1920s and produced a group of canoes with serial numbers in the 50K range. Number 50049 went on a green 17 foot long canoe from 1924. It is listed as a type A5 but I've not been able to find any description of this type in either the Kennebec or Morris catalogs.
Therefore, my guess is that you may have the Kennebec / Morris with number 50049 shown on page 151 of volume three in the Kennebec ledgers. This was assigned to a 17 foot long Morris model A, type Mah (mahogany?) A5. It was planked by Roy on February 23rd, 1924 and the canvas covering was applied by Tuttle on the same day. Grant applied the first filler coat on February 23rd, 1924 and the second filler coat on March 8th, 1924. It was railed by Mansell on March 22nd, 1924. It had outside stems and the original color was green. It shipped to location "24-85" on May 2nd, 1924. This location is probably an order number but we don't currently have enough information to identify it.
The scans of these build records can be found by following the links at the attached thumbnail images below. The original Kennebec records are reproduced through the courtesy of the Maine State Museum.
The microfilms and scans of these records were created with substantial grants from the Wooden Canoe Heritage Association (WCHA). I hope that you will 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 your canoe. Is there any sign of an outside stem? Feel free to reply here if you have any other questions. Thanks,
