How many Anderson Kingfishers were under construction around 1982?

By 1978, 200 kit sets of the aircraft had been sold and 100 Kingfishers were reported under construction. The Anderson EA-1 Kingfisher is an American two-seat amphibian, designed and marketed for amateur construction. It was the work of Earl William Anderson, a Pan Am airline captain, who flew the prototype on 24 April 1969.

The aircraft is a shoulder-wing monoplane with a flying-boat hull and outrigger floats on struts. On the ground it uses retractable tailwheel landing gear. The single engine, with a tractor propeller, is mounted in a nacelle above the wing. Some builders use wings from a Piper Cub instead of building their own.

The aircraft were later marketed by Richard Warner Aviation, before becoming the Wings Unlimited Kingfisher in the late 1990s. There is also an improved-performance version known as the "Super Kingfisher".
