What a beauty. I love those sphinx decals. .... and I don't see any rust. This one will be a fun job to spiff up. Do you have the slide plate that appears to be missing? You probably can find a replacement for that without too much difficulty. I agree that yours is a 127 because I have a 27 and my bobbin winder is near the base of the machine. Have fun cleaning her up..... she's going to love being brought back to life.
