By using the search terms "sewing machine badged Mercury", I read a lot about the Goodrich Company that sold Mercury machines. The first hit tells how to identify the year of manufacture. One very interesting item was about them copying different machines, even going so far as to copy a Singer 12 and putting Singer on it. Of course, they lost in a court battle with Singer. From what I can see of that bobbin in the picture, it looks a lot like an M class, but I read that those were for industrial machines. It's like that Johnny Cash song about taking home auto parts from a Detroit auto factory job until he had enough to make his own hybrid car.
