One of Dayton Wright's projects to extend the life of DH-4 production after Armistice. The aircraft was stretched by a foot to make a cabin for two behind the pilot. One can only speculate why it was called the Honeymoon. How many were built is unknown but there may have been only one. A Honeymoon won the Aviation Country Club Trophy Race at Detroit in 1922.

The one and only T-4 Messenger. A single seater, contemporary reports say it started as a liaison aircraft for the army but switched to being a civil aircraft before the project was abandoned. Photo from: National Archives at College Park, Maryland

Dayton Wright used the DH-4 as the basis of several post World War I projects when military orders were cancelled. Nothing is known of the Sedan other than this photo was taken in early 1919. The location appears to be Deeds airfield which Dayton Wright used for test flying for aircraft built at its factory in nearby Moraine. Photo from: National Archives at College Park, Maryland
