The White Family Rotary or White FR was the first sewing machine produced by the White Sewing Machine Company using a rotary hook bobbin driver. It joined the successful White Vibrating Shuttle on White's expanding product line and eventually eclipsed it. It was originally sold as a treadle with cabinet or as a hand-crank with carrying case; later, add-on electric motors with foot or knee control were available pre-installed or as a field upgrade. Typical cost for this machine as a treadle with a cabinet was USD65 in 1909, which is about USD1532 adjusted.
