Uwe Posted January 18, 2017 Report Posted January 18, 2017 (edited) System 331 (Size 10) is indeed a candidate for my mystery needle, according to this Schmetz Needle Size Comparison Chart at Universal Sewing. In the Singer world it would be a size "30". The Singer 7-33 takes a needle 7x5 Size 31 that is one size bigger than mine, at 350 Nm or 3.5 mm thick.
