Very pretty! Now it makes me want to clean up mine! I have one just like that in the hoard. It's much much dirtier than yours but I wonder if the true shade of pink would come up as nice as the one you have with some elbow grease? Mine has the same case and everything although I have done no work at this point to learn the age of it.
Iirc, there is one just like it in the Japanese machines thread and instead of "Atlas" actually says "Brother" on the face of the machine.
