Vintage old-style Bernina 5-groove pintuck presser foot #588. Foot is not numbered, but I asked about it on patternreview.com and was told Bernina didn't always number its feet. So I understand them to be genuine Bernina, not generic feet. Compatible with vintage 4mm machines including 730 Record, 830 Record, 930 Record. Note: These feet are **not compatible** with the more modern Old Style feet used with machines like the Bernina 1008, even though they have the two goal posts at the top.
