My W&W sewing machines are wonderful to use. Although I have several 127x1 needles, I use MY1014 exclusively for my W&W 9s, D9s, Singer 9Ws. These MY1014? needles are stronger than the old 127x1 needles. I have a packet of DBX1 needles, but use?the?MY1014 when sewing.
I also own a a few W&W curved needle and a few W&W 8s,machines and a W&W 6, Singer 10W and Singer 12W102 industrial sewing machines. The late Graham Forsdyke believed the Wheeler & Wilson machines were the Rolls Royce of sewing machines.
