The Grumman JF "Duck" was a single-engine amphibious biplane. It first flew on 17 April 1934 and was produced from 1934 until 1936, when production switched to the J2F. The only obvious external clue to differ an JF from an early J2F is the deletion of the inter-aileron strut between the wings on the J2F.
The Duck's main pontoon was part of the fuselage, making it a flying boat, though it appears more like a standard aircraft with an added float.
It set an amphibian speed record in December 1934, at 191 mph (307 km/h).
