You'll love your little featherweight. I just finished oiling mine since I'll be using her while my big machine is in for service. I'm really looking forward to sewing with her. You should be able to find out when yours was made by looking up the serial number on the Singer website. You can find that number by taking off the plate on the bottom. You should probably do that anyway to clean and oil her. If you don't have an owner's manual I think they're available for download if you do a Google search.
I'd love to have one with the fancy scroll faceplate.
