Oh, wow. I recognize that Singer. My friend in first grade had one in his house. I remember playing with the, uh, pedal? His mom sewed through her fingernail once. Not while I was messing with it, though. I think I can remember how she would use the wheel on the right to help slow it down rapidly and then to make slow stitches while turning the cloth until she’d get to another straightaway and could let fly.
“pedal?”
treadle ;o)
yup. Best control, best sewing and very soothing - the steady rocking with your feet on the treadle
