The Kennebec with number 10304 is a 17' Square Stern, so probably not it.
The one with 103040 is a 17' Kineo Special. It was built between March, 1931 and June, 1931. The color it was painted was not indicated. It was shipped June 20, 1931 to 31-433 - we don't have a way to crack that code, but it was probably a retailer, or perhaps a camp, as at least one other canoe was shipped to the same customer the same day.
