This is the largest needle I have found. You have to search a bit more to find size 19 (120), but 18 (110) is in the standard selection where they sell needles. The older machines take these needles fine. There is a Chinese brand that carries up to size 122 (140), but not all machines can take them. These needles are of reasonable quality. I know the old cast iron straight stitchers take them, as well as my Elna Supermatic (beige and tan as well as the green ones). The cocrete grey Pfaffs take them too. My 730 Bernina does not. If you ever should be tempted to try them out, make sure there's enough clearing for the hook and race as the needle goes up and down.
