The Kennebec canoe with serial number 19548 is shown on page 104 of volume number three in the Kennebec ledgers. This was assigned to a 15 foot long Kennebec Model, type a. It was planked by Cameron on October 29th, 1927. The canvas covering and first filler coat were applied by Roy on the same day. The second filler coat was applied by Thibodeau on November 12th, 1927. The rails were applied by Maucell on November 26th, 1927. The original color was green and it shipped to location 28-670 on June 18th, 1928. This location is probably an order number but we don't currently have enough information to identify it.
