The short, angular shoulders of the blade with the relative straight sides in the part visible above the waterline, seem similar to Cree style paddles. In particular, check out the screenshots from Cree Hunters of the Mistassini - the blade profile looks similar to Sam Blacksmith's green painted paddle. The elongated roll grip is also reminiscent of antique Cree Paddle posted on the Cherry Gallery site a while back.
