Just yesterday I bought a machine that has almost the same features... the bobbin area, 2 buttons to drop the feed dogs, bobbin winder, identical fly wheel, identical foot pedal, it even has the same 3 screws near the foot plate (2 are removed to lift the foot plate). These features are Singer-esqe, for lack of a better word. I don't know much about my machine either but thought I'd say "great find!". Your mechanical controls are arranged a little different than mine.
One of the slide knobs near the bobbin winder does the needle left-center-right function. Mine has this but it's on the top of the machine.
($75 is way too much for this machine, IMHO. Mine had a $75 price tag as well and I talked them down to $30)
