My guess is that you may have the Kennebec canoe with number 16652. This is a 16 foot long "KS" model as shown on page 180 of volume three in the Kennebec ledgers. It was planked by Polgorskoy on September 22nd, 1922. The canvas covering and first filler coat were applied by Tuttle on September 30th, 1922. Thibodeau applied the second filler coat on October 20th, 1922. It was railed by Grant on June 23rd, 1923. The original color was green. It shipped on June 23rd, 1923 to location 23-499. This location is probably an order number but we don't currently have enough information to identify it.
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) as you probably know well. 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. Now you can decide if "KS" stood for "K Special," "Kineo Special," Kennebec sponson, Kennebec sailing, or something else. Feel free to reply here if you have any other questions. Good luck with the restoration,
Benson
