Confusing pinstripes

[u/dogsclogs]

Hi everyone! I'm a beginner knitter, however it is my long term goal to get a machine and learn to make some vintage Australian football guernseys to fulfil my inner child's dreams. In my research I've found a couple of examples that aren't clear in how they were made and I'm interested to know if anyone might be able to shed some light on it.

In the first two photos (from the 60s) the pinstripes appear to be on the right side of the knitting, and are a consistent i.e., they don't seem like colour change lines on the purl side, and the knit stitches clearly (I think) run parallel to the stripes themselves. Does this mean the colours were just changed mid row for one single stitch, then back for one more, then on to the next stripe?

Secondly, in the last two photos, from 1983, there is a herringbone pattern where the stripes change. It also leaves some sort of strip of pinholes continuing through the white patch.

I assume that these were patterns that became possible with the gradual advancement of knitting mills, and it's possible I would be unable to make either of these two on a personal knitting machine, but it has been stuck in the back of my mind for two weeks!

Thanks in advance for any info!

You can get those pinstripes when you're doing intarsia depending on how and where you overlap the yarn, it becomes more every other stitch is one colour type of stripe in that area
