I got an email from a friend letting me know that the bobbin I was questioning in a post earlier this month is an S&M Bobbin. Now that he mentioned it, I remember that there were letters engraved on one of the bobbin ears. The engraving actually isn't all that noticable, unless you get the ight just right (see below.)
It is my understanding that these upgraded models with their fancy wood handles are made by Wasatch. I read somewhere that Wasatch bought the rights to manufacture the bobbins.
