The seller of this vehicle knew very little about it's history. It is believed the vehicle was built at the Grumman aircraft facility in Witchita KS in the late 40's to early 50's.
The seller had these original black and photos that were included in the sale. The photos listed the names of the builders from left to right as: Cameron Baily, Max Ray, Kelly Krentz, and A.A. Reddy.
While reminiscent of the Taylor Aerocar, it's definitely not an Aerocar.
