Kenmore 1602 photo on left, with 1601 to the right (not all of 1601 shows)

1601 dials, note the slender needleplate with a single hold on the left, of one end, for straight stitching, flip it to the other end, for zigzag stitches. It is difficult to see, with the presser foot in the way, but sometimes, you can find this needleplate on Ebay, in sets of  Kenmore accessories for sale, if your machine is missing the slender needle coverplate. Upper left dial stitch width, right top dial is for short, medium, or long stitch modification, on stretch stitches, upper large dial is stitch length & reverse in the center, lower large dial is stitch selector, as well as having a cam setting, for when using the type C stitch cams. Note the feed dog control, and light switch are on the bed of the machine.

1601 is CENTER HOMING NEEDLE

WON'T STAY IN STRAIGHT STITCH OR ZIGZAG

STITCH WIDTH DIAL TURNS BY ITSELF!

A wonderful individual, David Goboff, created a Kenmore sewing machine Model Chart which helps tell what each model can do, and what accessories originally came with them. Here is a link to his chart.
