The Boeing Model 204 was an American flying-boat aircraft built by Boeing in 1929. On the surface the 204 looked identical to the Boeing Model 6E but a number of internal changes including increasing the passenger capacity to 4 gave it a new Type Certificate and model number. Construction was started on five aircraft but only 2 were completed. The first designated 204 and the second 204A. A third aircraft was built by a private owner who had bought the 3 incomplete machines.
Made by Boeing.
It is the successor of the Boeing Model 6E .
