WB,
Without better images I don't have any guesses, but, being a bit familiar with both Seligas and Rehbeins, I'm reasonably confident it's not one of either.
I'd also comment that in the past in the Wis and MN region, there were a lot of small shops making canoes, most I/we? have never heard of.
A few years ago, I looked at a canoe in the Ely area that while, very well made and very nice lines, I couldn't identify and had no idea who made it. This canoe was in very nice condition and on maybe it's 3rd owner, who had had it many years.
