Boeing Model 204
Externally, the 204 looked identical to the Boeing Model 6E, but a number of internal changes, including increasing the passenger capacity to four, gave it a new type certificate and model number.A third aircraft was built by a private owner who had bought the three incomplete machines.The 204A was a dual-control version which was later owned by Peter Barnes, who flew it on his private Seattle-Victoria, British Columbia main run.[2] The C-204 Thunderbird, a modified 204, was the first type produced by Boeing Aircraft of Canada.Media related to Boeing model 204 at Wikimedia Commons
