I too learned on my late mother's 1947 FW, which I now have. I even have the original receipt... $49.00.
I like it mainly (for piecing) because the feed dogs are longer (than my "new" 1969 Singer) and grab the material easily to begin sewing. It's quiet; it hums; it sews evenly. I had one tiny problem with the bobbin placement, but it was fixed (by a professional) within a minute!
To me this one is PRICELE$$ and will go to my DGD someday.
