Jon,
This machine appears to be the same as the New Royal model SB. Looks exactly the same except for the decals, and a shield above the bobbin winder. So far, all I've found is a picture of the New Royal SB.
If this machine uses 15x1 needles that would make things easier. I'll try them first.
I would love to get some information on the foot controller before I take it apart. It is always helpful to know what you are looking at and what you should look for. I'll start with the motor and make sure it works and maybe by then I'll have some understanding of this kind of controller.
This will be a bit of an adventure. I'm used to the well-documented Singers, so I feel like I'm flying blind here, but sewing machine aren't so different from each other so I'm sure it will be fine.
