I have seen it called that. "The Pace/Mansdorf or Gannet conversion of the Widgeon with the Lycoming 300 hp. radial engines made it look very much like the Goose."
My photo has it as the Pace Gannet. In Aerofiles, it is listed under Gannet:
<small>Gannet Aircraft Inc, Sun Valley CA.</small> Super Widgeon c.1955 = STOL modification of Grumman Widgeon; load: 1700# v: 190/170/x range: 1000 (on 158 gallons of fuel). Claimed water take-off in 10 seconds.
Anyhoo, over to you PH!
