Here's one you don't see too often. She's a Singer 431g, made in Germany.
She may look very familiar to you, because she's basically a Singer 401A, mechanically identical (mostly) to the 401 but with a fold-up, slide-off sewing bed that makes this machine into a free-arm machine, ideal for sewing pant legs, shirt sleeves, etc.
Her Space Age styling with it's Flash Gordon-style fin, light cover, and exhaust-port-flame hand wheel, are a precursor to the fabulous Singer 500 Rocketeer.
Her fold-down bed extension adds lots of sewing surface to support your project, then flips up for compact storage, and secreted in the slide-off bed extension is a fully-loaded accessory tray with a flip-up lid. Inside, you'll find bobbins, pattern cams, needle plates, sewing feet (even a darning foot), and a selection of screwdrivers, pliers, and needle threader.
She uses standard needles and class 66 bobbins, which you can find all over the internet and from your local sewing store, and she sews straight-stitch, zigzag, and a slew of decorative and utility stitches.
She was in beautiful condition when we found her, but we still had to take her apart to clean off the sticky, dried-on oil and dust inside that keeps the parts from spinning, slipping, and sliding against each other like they used to.
Her parts went into the alcohol bath to be scrubbed, then inspected and polished before reassembly.
Now she's clean inside and out, and adjusted and tested until she's sewing beautifully.
Sorry to say, This one has SOLD!
