Edit: found Pima's page on it which has picture which shows that it is, but I'm not seeing explanation, http://www.pimaair.org/aircraft-by-n...-j4f-2-widgeon

Grumman Widgeon, March 1967 American Modeler - Airplanes and Rockets

I didn't take any pictures, but they also have a second lower hull on display against the wall behind the Widgeon. For years I wondered what it was. It was bright yellow, and looked too big to be a pontoon, except maybe for a C-47, but it was open topped. This trip, they finally put up a sign explaining what it was: a test hull for the Widgeon.

I was just thinking back to the first time I went there, when they had 1 hanger, the XJL-1 and SR-71 were still outside, and you could climb up and look inside the cockpits of the SR-71,
