I checked the numbers again and they are fairly legible as 11451 and 11452 both followed by 16. They are 16' long, 35" wide and 12 3/3" deep. The ribs are 1 7/8" x 3/8" with no taper. The tips of most ribs have a slight chamfer. The ribs are 1 7/8 to 2" apart.
The photos show that the bow and stern profile is different. This is explained in #2 as the stem has been replaced. The stems are short, under the decks by a full rib's width. The seats and thwarts are not in the same location in both canoes. The thwarts in #1 look original. It could be that the inwales in #2 have also been replaced as the screw holes for the thwarts and seats are not all centered.
The trim pieces are pretty chunky, not like the Skowhegans that we'vs seen, but these too could be replacements. There are no shadows of decals but #2 has 2 holes in the stern deck and a rectangular shadow.
So as the numbers don't match Kennebecs, I guess these are probably Skowhegans.
Both canoes need much work and will be great projects for their new owners. The owner has offered them for free and we'll post them in the classified "free" section with a description of their conditions.
