Here's another one. This one says "VERBETERD SINGER" which translates to "improved Singer". There is a name on the arm but I can't make it out ???MANN? That's the first word so it doesn't look like F&R, but I don't know. I think I remember reading that Singer successfully sued all these clone-makers.
