The Carleton canoe with this serial number is 18 feet long so that probably isn't yours. My guess is that you have a Kennebec canoe with serial number 19609. This is shown on page 121 of volume number three in the Kennebec ledgers. It was assigned to a 16 foot long Kennebec Model, type a. It was planked by Morgan on December 10th, 1927. The canvas covering and first filler coat were applied by Roy and sponsons by McInnis on the same day. The second filler coat was applied by Thibodeau on December 24th, 1927. The rails were applied by Ciuie (?) on December 31th, 1927. The original color was gray and it shipped to location 28-213 on April 3rd, 1928. This location is probably an order number but we don't currently have enough information to identify it.
