In 1938 the Reggiane Re.2000 was designed by Roberto Longhi and Antonio Alessio. Longhi had worked in the United States in the mid-1930s and based on his experience the Reggiane Re.2000 was a copy of the Sikorsky P-35.
The Re.2000 was all metal.
The Re.2000 proved equal to the G.50 and M.C.200 but wasn't liked by the military.
The fuel tanks for the Re.2000 were located in the wings. The military felt that this made the Re.2000 too vulnerable.
The tail wheel was retractable. The landing gear retracted backwards into the wing.
