Remarks by Johan Visschedijk: "One of the world's first successful small, personal airplanes, and also known as the SP-1, this single-seat type was produced by the Irwin Aircraft Company of Sacramento, California, USA. Of wooden construction and powered by a 25 hp Irwin Meteor motor, some forty aircraft were produced at Irwin airport, while an unknown additional number were sold as kits."
