Ha, you're correct!Canuck has a yoke. I think it would be called a yoke despite being large.
I've seen Carrie refer to it as an action seam.By split seam I meant the gusseted seam (is that the right word?). I like the back arrangement of the Canuck the best, and the simplicity of the Brakeman. My only criticism of the Work Coat is that, from the back, it looks like a long Speedway.
