I haven’t been able to find it either. It looks like the purl sts may be slipped on a row while knitting the knits. That lets the knits bulge out to the front.
not sure if this is any help
it is called speckled rib st and is as follows
Skill: intermediate
Multiple of 2 sts + 1
ROW 1 (RS): knit.
ROW 2: purl.
ROW 3: K1, *sl 1 purlwise, K1; rep from * to end.
ROW 4: K1, *yf, sl 1 purlwise, yb, K1; rep from * to end.
ROW 5: knit.
ROW 6: purl.
ROW 7: K2, *sl 1 purlwise, K1; rep from * to last st, K1.
ROW 8: K2, *yf, sl 1 purlwise, yb, K1; rep from * to last st, K1.
Repeat ROWS 1-8.
I didnt think the stitch I put up earlier looked quite right , so I got in touch with my MIL and she sent this link . Hope it helps

I think that’s it!!! Thank you so much! And especially for going the extra step to help me. I recently found a partially sweater I’d given up on many years ago and wanted to finish it but couldn’t remember the stitch. You saved me from the heartbreak of ripping the thing and starting over with another stitch!
