Yours looks exactly like my mom's machine. It also has a shuttle bobin like yours. My mom used hers until she passed away six years ago. It still runs like a top. Hers was issued from the elizabethtown plant in New Jersey in 1951.
I am going to do some special cleaning and replace the cord on it. I found a site to help me find some of the soft parts (belts and rubber for the bobin winder) and to guide me through the process. It is vintagesingers. A group from yahoo groups. If you are interested.
