Hard for me to see exactly what is going on with the seats, Zach. They don't appear to me to be the late-19th century Moroccoline (faux leather) seats that Morris offered, if that's what you're thinking. The Moroccoline (also referred to as Pantasote) seats are found on only two known Morrises, and those canoes pre-date serial numbering. This canoe dates to the middle teens, and I think someone padded the seats rather than re-caning them (I had a Penn Yan with a similar look).
Norm Sims brought his Morris with this type of seat to the 2016 assembly at Paul Smith's. When his canoe was restored by Tom Seavey, real leather was used to replace the Moroccoline. I'll attach a picture, which shows that the leather-part fills the center part of the seat (which otherwise would be caned) and doesn't rise up higher than the frame of the seat, as the cushion appears to do in divedog's pictures.
Some early ads for Morris refer to the imitation leather seats as Pantasote, and I'll share an ad that indicates folks didn't need to worry about their seats going up in flames if they were of this type.
Eh-- pictures won't upload. I'll try later...
