Stitch length is controlled by the lower right dial, reverse is a push button in the center of the dial. ZZ is up top with the enameled M in the center. I like the dial type stitch length controls much better than the lever type; it is just more intuitive.
A little clunky in the styling department but in person its very appealing. There is a very "Japanese" or at least 50's element in the styling that I would like to highlight, that is in the molding of the off-white, partially translucent control knobs. They have a very subtle milky white swirl to the plastic moldings that to some may look like a mistake but to others makes each machine unique. I think it counters some of the doughy 50's forms and adds an organic element to the final work.
I am starting to make simple wood frames for my in use machines and I have a secrete way of attaching them to the machine without those ridiculous looking plastic swing nuts that are on every portable case.
