I'm going to say/tell its a 1924 singer/99. If I could get a picture of mine to you. Some how. I would. Below your the singer manfg.co emblem should have, Im guessing--2 letters with 6 #'s. Mine is AA009802.. Let me know, what you find out. What year, etc. I use mine, every so often. It still runs like its new. And the best thing, is a lady quilting friend gave it to me--FREE. Don
