Do you mean the Bushmaster 2000, a revised version of the Ford Tri-Motor? The late Bill Stout after World War 2 got a revised version into production and late in 1966 Aircraft Hydro-Forming Inc. completed a prototype called Bushmaster 2000. Deliveries were scheduled to begin in early 1972. It is similar to the Ford Tri-Motor with 1-2 crew and up to 23 passengers high density, with normal seating for 15 passengers.
Power is three 450 Hp Pratt & Whitney R-985-AN-1 or 14B piston-engines. N7501V is pictured in my reference.
