This is my vintage circa 1937 Singer 201P. Isn't she a beauty?
Stella (yes, I named her - doesn't she look like a Stella?) is really a joy to work on. It's amazing really that a machine 50+ years old still performs to a very high standard. I honestly think the stitches she produces are the most uniform and precise I've seen comparable to any modern machine.
I've overcome the issue of not having a 1/4 inch foot by using a magnet barrier to the right side of the needle made specifically for the purpose of keeping an accurate measurement along the fabric as you sew. I bought this simple little device years and years ago after I purchased my other vintage Singer (1922 Singer hand rank). I don't know if they're still available on the market. But even if they're not using a homemade magnet device would work. One really neat feature of Stella that modern machines appear to have forgone is instead of a foot pedal to run the needle, she has a heal pedal. I thought at first this was going to be awkward to use but its not at all. I actually find it more comfortable then a standard foot pedal. I can control the needles speed better using either my heal or adjusting the position of my foot, the centre area of my foot. And because Stella was made in the heyday of Bakealite manufacture, she has a weighty pedal that doesn't move about the way lightweight foot pedals do.
