Congratulations! She's a beauty! It looks like you have a centennial also (blue badge). That makes it even more special! Check out the book Featherweight 221 The Perfect Portable And Its Stitches Across History. Expanded Third Edition by Nancy Johnson-Srebro. This book will give you all the information you will need and then some. They are wonderful machines - I've adopted 6 of them and they all have something different and special about them. You will enjoy sewing on it - they sew like a dream!
