Welcome and congratulations, I suspect that your plate has an "M" preceding the serial number which was used to signify that the serial number was 102877. The Kennebec canoe with this serial number is shown on pages 220 and 221 of volume four in the Kennebec ledgers. It was assigned to an 16 foot long Kineo Special model that was planked by Morgan on July 19th, 1930. Leonard applied the canvas covering on the same day. Leonard applied the first filler coat on July 26th, 1930 and the second coat on August 2nd, 1930. It was railed by C. Toulouse on September 13th, 1930. The "F 22" (Function number 22 or the keel?), "F 24" (Function number 24 or the finish work), and "F 28" (Function number 28 or the painting) were completed by Thib. on the same day. The original color was red. It was packed by Leonard on September 20th, 1930 and shipped to location "31-290" on May 18th, 1931. 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. These 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). A description of the project to preserve other records like these 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 http://www.wcha.org/about-wcha

More information about this and other Kennebec models can be found in the Kennebec catalogs contained on the Historic Wood Canoe and Boat Company Catalog Collection available from http://www.wcha.org/store/historic-wood-canoe-and-boat-company-catalog-collection
in the WCHA store. The information at http://www.wcha.org/content/kennebec-boat-and-canoe-company
indicates that Kennebec closed around 1941.
It is also possible that you could have another number or manufacturer if this description doesn't match your canoe. Feel free to reply here if you have any other questions.
